USN-2174-1: Linux kernel (EC2) vulnerabilities
26 April 2014
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Several security issues were fixed in the kernel.
- linux-ec2 - Linux kernel for EC2
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)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
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.
