Red Hat Security Advisory 2012-1347-01
Posted Oct 10, 2012

Red Hat Security Advisory 2012-1347-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way socket buffers requiring TSO were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service.

Ubuntu Security Notice USN-1530-1
Posted Aug 13, 2012
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1530-1 - Andy Adamson discovered a flaw in the Linux kernel's NFSv4 implementation. A remote NFS server (attacker) could exploit this flaw to cause a denial of service. Steve Grubb reported a flaw with Linux fscaps (file system base capabilities) when used to increase the permissions of a process. For application on which fscaps are in use a local attacker can disable address space randomization to make attacking the process with raised privileges easier. Various other issues were also addressed.

Linux Kernel HFS Plus Buffer Overflow
Posted May 16, 2012
Authored by Timo Warns | Site pre-cert.de

PRE-CERT Security Advisory - The Linux kernel contains a vulnerability in the driver for HFS plus file systems that may be exploited for code execution or privilege escalation. A specially-crafted HFS plus filesystem can cause a buffer overflow via the memcpy() call of hfs_bnode_read() (in fs/hfsplus/bnode.c).
