USN-2174-1: Linux kernel (EC2) vulnerabilities

Releases

• Ubuntu 10.04

Packages

• linux-ec2 - Linux kernel for EC2

Details

A flaw was discovered in the Linux kernel's handling of the SCTP handshake. A
remote attacker could exploit this flaw to cause a denial of service
(system crash). (CVE-2014-0101)

An error was discovered in the Linux kernel's DCCP protocol support. A
remote attacked could exploit this flaw to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2014-2523)

Update instructions

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

Ubuntu 10.04

• linux-image-2.6.32-363-ec2 - 2.6.32-363.76

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.
