Description

This security bulletin contains information about 1 security vulnerability.


1) Cryptographic issues (CVE-ID: CVE-2012-5375)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The CRC32C feature in the Btrfs implementation in the Linux kernel before 3.8-rc1 allows local users to cause a denial of service (prevention of file creation) by leveraging the ability to write to a directory important to the victim, and creating a file with a crafted name that is associated with a specific CRC32C hash value.


Remediation

Install update from vendor's website.
