Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ti-omap4: Linux kernel for OMAP4

Details:

A bug was discovered in the XFS filesystem's handling of pathnames. A local
attacker could exploit this to crash the system, leading to a denial of
service, or gain root privileges. (CVE-2011-4077)

Nick Bowler discovered the kernel GHASH message digest algorithm
incorrectly handled error conditions. A local attacker could exploit this
to cause a kernel oops. (CVE-2011-4081)

Scot Doyle discovered that the bridge networking interface incorrectly
handled certain network packets. A remote attacker could exploit this to
crash the system, leading to a denial of service. (CVE-2011-4087)

A flaw was found in the Journaling Block Device (JBD). A local attacker
able to mount ext3 or ext4 file systems could exploit this to crash the
system, leading to a denial of service. (CVE-2011-4132)

A bug was found in the way headroom check was performed in
udp6_ufo_fragment() function. A remote attacker could use this flaw to
crash the system. (CVE-2011-4326)

Clement Lecigne discovered a bug in the HFS file system bounds checking.
When a malformed HFS file system is mounted a local user could crash the
system or gain root privileges. (CVE-2011-4330)

package versions:
