Red Hat Security Advisory 2013-1264-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A heap-based buffer overflow flaw was found in the Linux kernel's iSCSI target subsystem. A remote attacker could use a specially-crafted iSCSI request to cause a denial of service on a system or, potentially, escalate their privileges on that system. A flaw was found in the Linux kernel's Performance Events implementation. On systems with certain Intel processors, a local, unprivileged user could use this flaw to cause a denial of service by leveraging the perf subsystem to write into the reserved bits of the OFFCORE_RSP_0 and OFFCORE_RSP_1 model-specific registers.

These custom kernel packages include support for network namespaces, this support is required to facilitate advanced OpenStack Networking deployments. A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol implementation handled duplicate cookies. If a local user queried SCTP connection information at the same time a remote attacker has initialized a crafted SCTP connection to the system, it could trigger a NULL pointer dereference, causing the system to crash.

ae2f3459ec3bdf76b4bab9b9b1aed7e5bb62fecbaa5d70cf041846a180464d66Ubuntu Security Notice 1882-1 - Kees Cook discovered a flaw in the Linux kernel's iSCSI subsystem. A remote unauthenticated attacker could exploit this flaw to cause a denial of service (system crash) or potentially gain administrative privileges. An information leak was discovered in the Linux kernel when inotify is used to monitor the /dev/ptmx device. A local user could exploit this flaw to discover keystroke timing and potentially discover sensitive information like password length. Various other issues were also addressed.

A local user could exploit this flaw to discover keystroke timing and potentially discover sensitive information like password length. An information leak was discovered in the Linux kernel's tkill and tgkill system calls when used from compat processes. A local user could exploit this flaw to examine potentially sensitive kernel memory. Various other issues were also addressed.
