Ubuntu Security Notice USN-1330-1
January 13, 2012

linux-ti-omap4 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10

Summary:

Several security issues were fixed in the kernel.

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

Details:

Clement Lecigne discovered a bug in the HFS filesystem. A local attacker
could exploit this to cause a kernel oops. (CVE-2011-2203)

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)

A flaw was found in how the Linux kernel handles user-defined key types. An
unprivileged local user could exploit this to crash the system.
(CVE-2011-4110)

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)

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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.10:
linux-image-3.0.0-1206-omap4 3.0.0-1206.15

After a standard system update you need to reboot your computer to make
all the necessary changes.
