4df3d0a41e548c26a0c180b85a467afbFreeBSD Security Advisory - A vulnerability was discovered in the NTP server's parsing of configuration directives. A vulnerability was found in NTP, in the parsing of packets from the DPTS Clock. A vulnerability was discovered in the NTP server's parsing of configuration directives. A vulnerability was found in NTP, affecting the origin timestamp check function. A remote, authenticated attacker could cause ntpd to crash by sending a crafted message. A malicious device could send crafted messages, causing ntpd to crash. An attacker able to spoof messages from all of the configured peers could send crafted packets to ntpd, causing later replies from those peers to be discarded, resulting in denial of service.

0ff54b024b64c4bf409da6fc84703fecFreeBSD Security Advisory - If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. There is a carry propagating bug in the x86_64 Montgomery squaring procedure. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. Various other issues have also been identified.
61e028674e75cf79a6ef2b0daf4f97e0FreeBSD Security Advisory - The ssh-agent(1) agent supports loading a PKCS#11 module from outside a trusted whitelist. An attacker can request loading of a PKCS#11 module across forwarded agent-socket. When privilege separation is disabled, forwarded Unix domain sockets would be created by sshd(8) with the privileges of 'root' instead of the authenticated user. A remote attacker who have control of a forwarded agent-socket on a remote system and have the ability to write files on the system running ssh-agent(1) agent can run arbitrary code under the same user credential. Because the attacker must already have some control on both systems, it is relatively hard to exploit this vulnerability in a practical attack. When privilege separation is disabled (on FreeBSD, privilege separation is enabled by default and has to be explicitly disabled), an authenticated attacker can potentially gain root privileges on systems running OpenSSH server.

fce94472a944196f57b09c666a948569This Metasploit module exploits a shell command injection in the way "delegates" (commands for converting files) are processed in ImageMagick versions <= 7.0.1-0 and <= 6.9.3-9 (legacy). Since ImageMagick uses file magic to detect file format, you can create a .png (for example) which is actually a crafted SVG (for example) that triggers the command injection. Tested on Linux, BSD, and OS X. You'll want to choose your payload carefully due to portability concerns. Use cmd/unix/generic if need be.
673c4b90719c9b8a377e4c72d8396c29Core Security Technologies Advisory - An integer signedness error has been found in the amd64_set_ldt() function in the FreeBSD kernel code (define d in the /sys/amd64/amd64/sys_machdep.c file), which implements the i386_set_ldt system call on the amd64 version of the OS. This integer signedness issue ultimately leads to a heap overflow in the kernel, allowing local unprivileged attackers to crash the system. FreeBSD 10.2 amd64 is affected.
5fddced07d5ad899ebb2d9c6bf48f392FreeBSD Security Advisory - A cross-protocol attack was discovered that could lead to decryption of TLS sessions by using a server supporting SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle. Note that traffic between clients and non-vulnerable servers can be decrypted provided another server supporting SSLv2 and EXPORT ciphers (even with a different protocol such as SMTP, IMAP or POP3) shares the RSA keys of the non-vulnerable server. This vulnerability is known as DROWN. Various other issues were also addressed.
9ba68b8ddba8c9076b272b296999095cFreeBSD Security Advisory - Testing by ISC has uncovered a defect in control channel input handling which can cause named to exit due to an assertion failure in sexpr.c or alist.c when a malformed packet is sent to named's control channel (the interface which allows named to be controlled using the "rndc" server control utility). An error when parsing signature records for DNAME records having specific properties can lead to named exiting due to an assertion failure in resolver.c or db.c. A remote attacker can deliberately trigger the failed assertion if the DNS server accepts remote rndc commands regardless if authentication is configured. Note that this is not enabled by default. A remote attacker who can cause a server to make a query deliberately chosen to generate a response containing a signature record which would trigger a failed assertion and cause named to stop. Disabling DNSsec does not provide protection against this vulnerability.

7d1a99c3863b05856f67c2ccb39b1ae2The Install.framework runner suid root binary does not correctly account for the fact that Distributed Objects can be connected to by multiple clients at the same time. By connecting two proxy objects to an IFInstallRunner and calling [IFInstallRunner makeReceiptDirAt:asRoot:] in the first and passing a custom object as the directory name we can get a callback to our code just after the makeReceiptDirAt code has called seteuid(0);setguid(0) to regain privs. Since BSD priviledges are per-process this means that our other proxy object will now have euid 0 without having to provide an authorization reference. In this second proxy we can then just call runTaskSecurely and get a root shell before returning from the first proxy's callback function which will then drop privs.
56bffdab05f4e18e4e17316125e04b4eUbuntu Security Notice 2455-1 - It was discovered that bsd-mailx contained a feature that allowed syntactically valid email addresses to be treated as shell commands. A remote attacker could possibly use this issue with a valid email address to execute arbitrary commands. This functionality has now been disabled by default, and can be re-enabled with the "expandaddr" configuration option. This update alone does not remove all possibilities of command execution. In environments where scripts use mailx to process arbitrary email addresses, it is recommended to modify them to use a "--" separator before the address to properly handle those that begin with "-". Various other issues were also addressed.
a01c6cddbe1fbf6bfc8a2cbc8e906e31Debian Linux Security Advisory 3104-1 - It was discovered that bsd-mailx, an implementation of the "mail" command, had an undocumented feature which treats syntactically valid email addresses as shell commands to execute.
9d911bcd97ae2855a676663bdbc79aebMandriva Linux Security Advisory 2013-271 - The make include files in NetBSD before 1.6.2, as used in pmake 1.111 and earlier, allow local users to overwrite arbitrary files via a symlink attack on a /tmp/_depend##### temporary file, related to bsd.lib.mk and bsd.prog.mk.

b76bad368ea311677dabb0618ec6c8cfThis is a 64bit Mac OS-X kernel rootkit that uses no hardcoded address to hook the BSD subsystem in all OS-X Lion and below. It uses a combination of syscall hooking and DKOM to hide activity on a host. String resolution of symbols no longer works on Mountain Lion as symtab is destroyed during load, this code is portable on all Lion and below but requires re-working for hooking under Mountain Lion.
