Ubuntu Security Notice 2075-1 - Vasily Kulikov reported a flaw in the Linux kernel's implementation of ptrace. An unprivileged local user could exploit this flaw to obtain sensitive information from kernel memory. Dave Jones and Vince Weaver reported a flaw in the Linux kernel's per event subsystem that allows normal users to enable function tracing. An unprivileged local user could exploit this flaw to obtain potentially sensitive information from the kernel. Various other issues were also addressed.

Mandriva Linux Security Advisory 2013-265 - Multiple vulnerabilities has been found and corrected in the Linux kernel. The ipc_rcu_putref function in ipc/util.c in the Linux kernel before 3.10 does not properly manage a reference count, which allows local users to cause a denial of service via a crafted application. The skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel through 3.12 allows remote attackers to cause a denial of service via a small value in the IHL field of a packet with IPIP encapsulation. Various other issues have also been addressed.

Red Hat Security Advisory 2013-1490-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way IP packets with an Internet Header Length of zero were processed in the skb_flow_dissect() function in the Linux kernel. A remote attacker could use this flaw to trigger an infinite loop in the kernel, leading to a denial of service. A flaw was found in the way the Linux kernel's IPv6 implementation handled certain UDP packets when the UDP Fragmentation Offload feature was enabled. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system.
