The kernel packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues:
A flaw was found in the way socket buffers (skb) requiring TSO (TCP
segment offloading) 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. (CVE-2012-3412, Important)
A buffer overflow flaw was found in the hfs_bnode_read() function in the
HFS Plus (HFS+) file system implementation in the Linux kernel. A local
user able to mount a specially-crafted HFS+ file system image could use
this flaw to cause a denial of service or escalate their privileges.
(CVE-2012-2319, Low)
Red Hat would like to thank Ben Hutchings of Solarflare ™ for reporting
