6db36db0cf544b0d71fd346914fc4f771d7d6bf477af2e61c0f394af113ed5dfRed 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.

c3d61e0fb4aa4f5494b3cdd1af09f21f215af1156fd6bf715ccecb2845b2618aMandriva Linux Security Advisory 2013-194 - Multiple vulnerabilities has been found and corrected in the Linux kernel. net/ceph/auth_none.c in the Linux kernel through 3.10 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an auth_reply message that triggers an attempted build_request operation. The HP Smart Array controller disk-array driver and Compaq SMART2 controller disk-array driver in the Linux kernel through 3.9.4 do not initialize certain data structures, which allows local users to obtain sensitive information from kernel memory via a crafted IDAGETPCIINFO command for a /dev/ida device, related to the ida_locked_ioctl function in drivers/block/cpqarray.c or a crafted CCISS_PASSTHRU32 command for a /dev/cciss device, related to the cciss_ioctl32_passthru function in drivers/block/cciss.c. Various other issues have also been addressed. The updated packages provides a solution for these security issues.
