Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2015-0066-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer, Transport Layer Security, and Datagram Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. A NULL pointer dereference flaw was found in the DTLS implementation of OpenSSL. A remote attacker could send a specially crafted DTLS message, which would cause an OpenSSL server to crash. A memory leak flaw was found in the way the dtls1_buffer_record() function of OpenSSL parsed certain DTLS messages. A remote attacker could send multiple specially crafted DTLS messages to exhaust all available memory of a DTLS server.

FreeBSD Security Advisory - OpenSSL Updates
Posted Jan 15, 2015
Site security.freebsd.org

FreeBSD Security Advisory - A carefully crafted DTLS message can cause a segmentation fault in OpenSSL due to a NULL pointer dereference. A memory leak can occur in the dtls1_buffer_record function under certain conditions. When OpenSSL is built with the no-ssl3 option and a SSL v3 ClientHello is received the ssl method would be set to NULL which could later result in a NULL pointer dereference. An OpenSSL client will accept a handshake using an ephemeral ECDH ciphersuite using an ECDSA certificate if the server key exchange message is omitted. An OpenSSL client will accept the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. An OpenSSL server will accept a DH certificate for client authentication without the certificate verify message. OpenSSL accepts several non-DER-variations of certificate signature algorithm and signature encodings. OpenSSL also does not enforce a match between the signature algorithm between the signed and unsigned portions of the certificate. Bignum squaring (BN_sqr) may produce incorrect results on some platforms, including x86_64.

Mandriva Linux Security Advisory 2015-019 - A carefully crafted DTLS message can cause a segmentation fault in OpenSSL due to a NULL pointer dereference. This could lead to a Denial Of Service attack. A memory leak can occur in the dtls1_buffer_record function under certain conditions. In particular this could occur if an attacker sent repeated DTLS records with the same sequence number but for the next epoch. The memory leak could be exploited by an attacker in a Denial of Service attack through memory exhaustion. Various other issues have also been addressed. The updated packages have been upgraded to the 1.0.0p version where these security flaws has been fixed.

Mandriva Linux Security Advisory 2014-203
Posted Oct 24, 2014
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2014-203 - OpenSSL has added support for TLS_FALLBACK_SCSV to allow applications to block the ability for a MITM attacker to force a protocol downgrade. Some client applications will reconnect using a downgraded protocol to work around interoperability bugs in older servers. This could be exploited by an active man-in-the-middle to downgrade connections to SSL 3.0 even if both sides of the connection support higher protocols. SSL 3.0 contains a number of weaknesses including POODLE. When an OpenSSL SSL/TLS/DTLS server receives a session ticket the integrity of that ticket is first verified. In the event of a session ticket integrity check failing, OpenSSL will fail to free memory causing a memory leak. By sending a large number of invalid session tickets an attacker could exploit this issue in a Denial Of Service attack. The updated packages have been upgraded to the 1.0.0o version where these security flaws has been fixed.

FreeBSD Security Advisory - OpenSSL Vulnerabilities
Posted Oct 22, 2014
Site security.freebsd.org

FreeBSD Security Advisory - A flaw in the DTLS SRTP extension parsing code allows an attacker, who sends a carefully crafted handshake message, to cause OpenSSL to fail to free up to 64k of memory causing a memory leak. When an OpenSSL SSL/TLS/DTLS server receives a session ticket the integrity of that ticket is first verified. In the event of a session ticket integrity check failing, OpenSSL will fail to free memory causing a memory leak. The SSL protocol 3.0, as supported in OpenSSL and other products, supports CBC mode encryption where it could not adequately check the integrity of padding, because of the use of non-deterministic CBC padding. This protocol weakness makes it possible for an attacker to obtain clear text data through a padding-oracle attack. Some client applications (such as browsers) will reconnect using a downgraded protocol to work around interoperability bugs in older servers. This could be exploited by an active man-in-the-middle to downgrade connections to SSL 3.0 even if both sides of the connection support higher protocols. SSL 3.0 contains a number of weaknesses including POODLE.

IBM AIX Kernel Memory Leak / Denial Of Service
Posted May 6, 2014
Authored by Tim Brown | Site portcullis-security.com

IBM AIX versions 5.3, 6.1 and 7.1 releases VIOS 2.2.* suffer from kernel memory leak and denial of service vulnerabilities. It has been identified that the ptrace() system call can be manipulated by an unprivileged user into leaking uninitialized kernel memory and that the method by which this is achieved may also lead to a denial of service condition. This can be achieved by manipulating the parameters that are passed to the ptrace() system call when performing the PT_LDINFO operation. By calling ptrace(PT_LDINFO, childpid, leakbuffer, maximumleak, NULL) with a value of maximumleak that greater than that required for the expected result of the PT_LDINFO operation, the AIX kernel will xmalloc() this space (without initializing it), populate it and then perform a copy operation that returns the result within leakbuffer.

Mandriva Linux Security Advisory 2014-051 - It was discovered that file before 5.17 contains a flaw in the handling of indirect magic rules in the libmagic library, which leads to an infinite recursion when trying to determine the file type of certain files. Additionally, other well-crafted files might result in long computation times and overlong results. A flaw was found in the way the file utility determined the type of Portable Executable format files, the executable format used on Windows. A malicious PE file could cause the file utility to crash or, potentially, execute arbitrary code. A memory leak in file has also been fixed. The affected packages have been upgraded to the 5.12 version and patched to correct these flaws.

Cisco Security Advisory 20130925-ike
Posted Sep 25, 2013
Authored by Cisco Systems | Site cisco.com

Cisco Security Advisory - A vulnerability in the Internet Key Exchange (IKE) protocol of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a memory leak that could lead to a device reload. The vulnerability is due to incorrect handling of malformed IKE packets by the affected software. An attacker could exploit this vulnerability by sending crafted IKE packets to a device configured with features that leverage IKE version 1 (IKEv1). Although IKEv1 is automatically enabled on a Cisco IOS Software and Cisco IOS XE Software when IKEv1 or IKE version 2 (IKEv2) is configured, the vulnerability can be triggered only by sending a malformed IKEv1 packet. In specific conditions, normal IKEv1 packets can also cause an affected release of Cisco IOS Software to leak memory. Only IKEv1 is affected by this vulnerability. An exploit could cause Cisco IOS Software not to release allocated memory, causing a memory leak. A sustained attack may result in a device reload. Cisco has released free software updates that address this vulnerability. There are no workarounds to mitigate this vulnerability.
