Publication date

26 April 2014

Overview

Several security issues were fixed in the kernel.

Releases

Packages

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

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.

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.

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