USN-2259-1: Linux kernel vulnerabilities
27 June 2014
Several security issues were fixed in the kernel.
Releases
Packages
- linux - Linux kernel
Details
Salva Peiró discovered an information leak in the Linux kernel's media-
device driver. A local attacker could exploit this flaw to obtain sensitive
information from kernel memory. (CVE-2014-1739)
A bounds check error was discovered in the socket filter subsystem of the
Linux kernel. A local user could exploit this flaw to cause a denial of
service (system crash) via crafted BPF instructions. (CVE-2014-3144)
A remainder calculation error was discovered in the socket filter subsystem
of the Linux kernel. A local user could exploit this flaw to cause a denial
of service (system crash) via crafted BPF instructions. (CVE-2014-3145)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04
-
linux-image-3.2.0-65-highbank
-
3.2.0-65.98
-
linux-image-3.2.0-65-virtual
-
3.2.0-65.98
-
linux-image-3.2.0-65-powerpc64-smp
-
3.2.0-65.98
-
linux-image-3.2.0-65-generic-pae
-
3.2.0-65.98
-
linux-image-3.2.0-65-omap
-
3.2.0-65.98
-
linux-image-3.2.0-65-generic
-
3.2.0-65.98
-
linux-image-3.2.0-65-powerpc-smp
-
3.2.0-65.98
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.
