USN-1332-1: Linux kernel (Maverick backport) vulnerabilities
13 January 2012
Several security issues were fixed in the kernel.
Releases
Packages
- linux-lts-backport-maverick - Linux kernel backport from Maverick
Details
Peter Huewe discovered an information leak in the handling of reading
security-related TPM data. A local, unprivileged user could read the
results of a previous TPM command. (CVE-2011-1162)
Dan Rosenberg reported an error in the old ABI compatibility layer of ARM
kernels. A local attacker could exploit this flaw to cause a denial of
service or gain root privileges. (CVE-2011-1759)
Ben Hutchings reported a flaw in the kernel's handling of corrupt LDM
partitions. A local user could exploit this to cause a denial of service or
escalate privileges. (CVE-2011-2182)
Clement Lecigne discovered a bug in the HFS filesystem. A local attacker
could exploit this to cause a kernel oops. (CVE-2011-2203)
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)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 10.04
-
linux-image-2.6.35-32-virtual
-
2.6.35-32.64~lucid1
-
linux-image-2.6.35-32-server
-
2.6.35-32.64~lucid1
-
linux-image-2.6.35-32-generic-pae
-
2.6.35-32.64~lucid1
-
linux-image-2.6.35-32-generic
-
2.6.35-32.64~lucid1
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
