Publication date
8 December 2011
Overview
Several security issues were fixed in the kernel.
Releases
Packages
- linux - Linux kernel
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)
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)
Update instructions
After a standard system update you need to reboot your computer to make all the necessary changes.
Learn more about how to get the fixes.The problem can be corrected by updating your system to the following package versions:
Reduce your security exposure
Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
