A remote attacker could use this flaw to bypass intended mod_security restrictions, allowing them to send requests containing content that should have been removed by mod_security.
23f22694518c71f067c9915413f641361265e421bf51568bbf400fe91d29e5e1Mandriva Linux Security Advisory 2015-103 - Due to incorrect state management, Squid before 3.3.12 is vulnerable to a denial of service attack when processing certain HTTPS requests if the SSL-Bump feature is enabled. Matthew Daley discovered that Squid 3 did not properly perform input validation in request parsing. A remote attacker could send crafted Range requests to cause a denial of service. Due to incorrect buffer management Squid can be caused by an attacker to write outside its allocated SNMP buffer. Due to incorrect bounds checking Squid pinger binary is vulnerable to denial of service or information leak attack when processing larger than normal ICMP or ICMPv6 packets. Due to incorrect input validation Squid pinger binary is vulnerable to denial of service or information leak attacks when processing ICMP or ICMPv6 packets.
b3a7102719ad1db82c04532795f87002757f84b9b74f8c08a14cd808e53dcbccMandriva Linux Security Advisory 2015-104 - The libdw library provides support for accessing DWARF debugging information inside ELF files. An integer overflow flaw in check_section(), leading to a heap-based buffer overflow, was found in the libdw library. A malicious ELF file could cause an application using libdw to crash or, potentially, execute arbitrary code with the privileges of the user running the application. Directory traversal vulnerability in the read_long_names function in libelf/elf_begin.c in elfutils allows remote attackers to write to arbitrary files to the root directory via a / in a crafted archive, as demonstrated using the ar program.
2dc0f5478ae8a0416760b54f46eda2b4b9a524956ed6d38ef3797a37480e1da1Mandriva Linux Security Advisory 2015-102 - Florian Weimer reported that the printbuf APIs used in the json-c library used ints for counting buffer lengths, which is inappropriate for 32bit architectures. These functions need to be changed to using size_t if possible for sizes, or to be hardened against negative values if not. This could be used to cause a denial of service in an application linked to the json-c library. Florian Weimer reported that the hash function in the json-c library was weak, and that parsing smallish JSON strings showed quadratic timing behaviour. This could cause an application linked to the json-c library, and that processes some specially-crafted JSON data, to use excessive amounts of CPU.
53220f408dd775184b66dbae8a641480a35b07f26f6e64a9d1156a34f96373cbMandriva Linux Security Advisory 2015-101 - Florian Weimer found a stack-based buffer overflow flaw in the libjbig library (part of jbigkit). A specially-crafted image file read by libjbig could be used to cause a program linked to libjbig to crash or, potentially, to execute arbitrary code. The jbigkit package has been updated to version 2.1, which fixes this issue, as well as a few other bugs, including the ability of corrupted input data to force the jbig85 decoder into an end-less loop.
0eef4cdfaf4e18da84306809e2310c9f65932487688f820380f590e6d610fa60Mandriva Linux Security Advisory 2015-100 - Florian Weimer discovered that cups-filters incorrectly handled memory in the urftopdf filter. An attacker could possibly use this issue to execute arbitrary code with the privileges of the lp user. Florian Weimer discovered that cups-filters incorrectly handled memory in the pdftoopvp filter. Various other issues where also addressed.
7f312cada7ef4fe1709a37c3131bcc60a0c6ae0baefe7518dff2e7a96f7746caMandriva Linux Security Advisory 2015-098 - Paras Sethia discovered that libcurl would sometimes mix up multiple HTTP and HTTPS connections with NTLM authentication to the same server, sending requests for one user over the connection authenticated as a different user. libcurl can in some circumstances re-use the wrong connection when asked to do transfers using other protocols than HTTP and FTP, causing a transfer that was initiated by an application to wrongfully re-use an existing connection to the same server that was authenticated using different credentials. Various other issues were also addressed.
238c9d05fcd4c3b08f5247b6e8c3855e7a760b684bb0b2f4b2fd169a52c9dffcMandriva Linux Security Advisory 2015-096 - A flaw was found in the way stunnel, a socket wrapper which can provide SSL support to ordinary applications, performed initialization of PRNG after fork. When accepting a new connection, the server forks and the child process handles the request. The RAND_bytes() function of openssl doesn't reset its state after the fork, but seeds the PRNG with the output of time. The most important consequence is that servers using EC or DSA certificates may under certain conditions leak their private key. The updated packages fix this issue by using threads instead of new processes to handle connections. Also an issue has been corrected where the directory for the pid file was not being created when the package is installed. An issue currently exists in Mageia 4 where it fails trying to use FIPS SSL. This can be worked around by adding fips = no into the config.
7dce4ccd27d3ab24aaba38df63d58ff30f2afcc77eb744241fcc74995ab0f4ecMandriva Linux Security Advisory 2015-095 - sshd in OpenSSH before 6.6 does not properly support wildcards on AcceptEnv lines in sshd_config, which allows remote attackers to bypass intended environment restrictions by using a substring located before a wildcard character. Matthew Vernon reported that if a SSH server offers a HostCertificate that the ssh client doesn't accept, then the client doesn't check the DNS for SSHFP records. As a consequence a malicious server can disable SSHFP-checking by presenting a certificate.
704f97d77be07b02b98aa395298a8190003a67ae5101733fa1d6b66750ddbc2aMandriva Linux Security Advisory 2015-099 - Jakub Wilk discovered that temporary files were insecurely created (via mktemp()) in the IptcImagePlugin.py, Image.py, JpegImagePlugin.py, and EpsImagePlugin.py files of Python Imaging Library. A local attacker could use this flaw to perform a symbolic link attack to modify an arbitrary file accessible to the user running an application that uses the Python Imaging Library. Jakub Wilk discovered that temporary files created in the JpegImagePlugin.py and EpsImagePlugin.py files of the Python Imaging Library were passed to an external process. These could be viewed on the command line, allowing an attacker to obtain the name and possibly perform symbolic link attacks, allowing them to modify an arbitrary file accessible to the user running an application that uses the Python Imaging Library. The Python Imaging Library is vulnerable to a denial of service attack in the IcnsImagePlugin. Python Image Library 1.1.7 and earlier and Pillow 2.3 might allow remote attackers to execute arbitrary commands via shell metacharacters, due to an incomplete fix for CVE-2014-1932. Pillow before 2.7.0 and 2.6.2 allows remote attackers to cause a denial of service via a compressed text chunk in a PNG image that has a large size when it is decompressed.
092f936217614b5a74ef335be07ec92dfa5bda4cb5a5121f9729ecadf91379dfMandriva Linux Security Advisory 2015-097 - XML eXternal Entity flaws were discovered in the Zend Framework. An attacker could use these flaws to cause a denial of service, access files accessible to the server process, or possibly perform other more advanced XML External Entity attacks. Using the Consumer component of Zend_OpenId, it is possible to login using an arbitrary OpenID account (without knowing any secret information) by using a malicious OpenID Provider. That means OpenID it is possible to login using arbitrary OpenID Identity (MyOpenID, Google, etc), which are not under the control of our own OpenID Provider. Thus, we are able to impersonate any OpenID Identity against the framework ,. The implementation of the ORDER BY SQL statement in Zend_Db_Select of Zend Framework 1 contains a potential SQL injection when the query string passed contains parentheses. Due to a bug in PHP's LDAP extension, when ZendFramework's Zend_ldap class is used for logins, an attacker can login as any user by using a null byte to bypass the empty password check and perform an unauthenticated LDAP bind. The sqlsrv PHP extension, which provides the ability to connect to Microsoft SQL Server from PHP, does not provide a built-in quoting mechanism for manually quoting values to pass via SQL queries; developers are encouraged to use prepared statements. Zend Framework provides quoting mechanisms via Zend_Db_Adapter_Sqlsrv which uses the recommended double single quote as quoting delimiters. SQL Server treats null bytes in a query as a string terminator, allowing an attacker to add arbitrary SQL following a null byte, and thus create a SQL injection.
dbd355d47d2272372963e41921faec57d94a89afaed8462832c6a5dd1b7b545cMandriva Linux Security Advisory 2015-090 - The png_push_read_chunk function in pngpread.c in the progressive decoder in libpng 1.6.x through 1.6.9 allows remote attackers to cause a denial of service via an IDAT chunk with a length of zero. libpng versions 1.6.9 through 1.6.15 have an integer-overflow vulnerability in png_combine_row() when decoding very wide interlaced images, which can allow an attacker to overwrite an arbitrary amount of memory with arbitrary data.
721892150da01f6313a1b99a68e76de5d0f151f714d22a4bb6438918cbb8aa9bMandriva Linux Security Advisory 2015-094 - A bug in the experimental SPDY implementation in nginx was found, which might allow an attacker to cause a heap memory buffer overflow in a worker process by using a specially crafted request, potentially resulting in arbitrary code execution. Antoine Delignat-Lavaud and Karthikeyan Bhargavan discovered that it was possible to reuse cached SSL sessions in unrelated contexts, allowing virtual host confusion attacks in some configurations by an attacker in a privileged network position.

19a31025ffbf8447f6cdb3bb70ede57e8f0dce94fcd7cd5d396da9f7fdab3fc1Mandriva Linux Security Advisory 2015-092 - Remotely exploitable denial of service vulnerability in Net-SNMP, in the Linux implementation of the ICMP-MIB, making the SNMP agent vulnerable if it is making use of the ICMP-MIB table objects. Remotely exploitable denial of service vulnerability in Net-SNMP, in snmptrapd, due to how it handles trap requests with an empty community string when the perl handler is enabled. A remote denial-of-service flaw was found in the way snmptrapd handled certain SNMP traps when started with the -OQ option. If an attacker sent an SNMP trap containing a variable with a NULL type where an integer variable type was expected, it would cause snmptrapd to crash.

It is also vulnerable to a cross site request forgery vulnerability that allows creating new administrative users.
574fe6d4c54586156bb4f27078d034bf2e81e5dc942e3eff6ea39230993dfecaMandriva Linux Security Advisory 2015-085 - The mod_dav_svn module in Apache Subversion before 1.8.8, when SVNListParentPath is enabled, allows remote attackers to cause a denial of service via an OPTIONS request. Ben Reser discovered that Subversion did not correctly validate SSL certificates containing wildcards. A remote attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. Bert Huijben discovered that Subversion did not properly handle cached credentials. A malicious server could possibly use this issue to obtain credentials cached for a different server. A NULL pointer dereference flaw was found in the way mod_dav_svn handled REPORT requests. A remote, unauthenticated attacker could use a crafted REPORT request to crash mod_dav_svn. A NULL pointer dereference flaw was found in the way mod_dav_svn handled URIs for virtual transaction names. A remote, unauthenticated attacker could send a request for a virtual transaction name that does not exist, causing mod_dav_svn to crash.

A malicious, local user could use this flaw to create a specially-crafted directory structure that could lead to arbitrary code execution with the privileges of the udisks daemon.
89427775961b055b7bc854212860e0b2ce0aed3a1fb8aec848745d9bd506973aMandriva Linux Security Advisory 2015-086 - When using libssh before 0.6.3, a libssh-based server, when accepting a new connection, forks and the child process handles the request. The RAND_bytes() function of openssl doesn't reset its state after the fork, but simply adds the current process id to the PRNG state, which is not guaranteed to be unique. The most important consequence is that servers using EC or DSA certificates may under certain conditions leak their private key. Double free vulnerability in the ssh_packet_kexinit function in kex.c in libssh 0.5.x and 0.6.x before 0.6.4 allows remote attackers to cause a denial of service via a crafted kexinit packet.
05034794c69e38df2effbf7e99ba466e4bdd8cd1c06e90c7380ffd81a37a83d6Mandriva Linux Security Advisory 2015-084 - An updated tomcat package fixes multiple security vulnerabilities.
64e66ca878e099d017de20173c80aa4b21ef506d6441fa3365891cde5f40850eMandriva Linux Security Advisory 2015-082 - In Samba before 3.6.23, the SAMR server neglects to ensure that attempted password changes will update the bad password count, and does not set the lockout flags. This would allow a user unlimited attempts against the password by simply calling ChangePasswordUser2 repeatedly. This is available without any other authentication. Information leak vulnerability in the VFS code, allowing an authenticated user to retrieve eight bytes of uninitialized memory when shadow copy is enabled. Samba versions before 3.6.24, 4.0.19, and 4.1.9 are vulnerable to a denial of service on the nmbd NetBIOS name services daemon. A malformed packet can cause the nmbd server to loop the CPU and prevent any further NetBIOS ame service. Samba versions before 3.6.24, 4.0.19, and 4.1.9 are affected by a denial of service crash involving overwriting memory on an authenticated connection to the smbd file server. An uninitialized pointer use flaw was found in the Samba daemon (smbd). A malicious Samba client could send specially crafted netlogon packets that, when processed by smbd, could potentially lead to arbitrary code execution with the privileges of the user running smbd (by default, the root user).
a746da07e0936d2f90ff3113f5c91d8a56d359101e9fd3c4b400291184eac8c7Mandriva Linux Security Advisory 2015-083 - Samba 4.0.x before 4.0.24, 4.1.x before 4.1.16, and 4.2.x before 4.2rc4, when an Active Directory Domain Controller is configured, allows remote authenticated users to set the LDB userAccountControl UF_SERVER_TRUST_ACCOUNT bit, and consequently gain privileges, by leveraging delegation of authority for user-account or computer-account creation. An uninitialized pointer use flaw was found in the Samba daemon (smbd). A malicious Samba client could send specially crafted netlogon packets that, when processed by smbd, could potentially lead to arbitrary code execution with the privileges of the user running smbd (by default, the root user). The updated packages provides a solution for these security issues.
