Published: 23 June 2014

The __do_follow_link function in fs/namei.c in the Linux kernel before 2.6.33 does not properly handle the last pathname component during use of certain filesystems, which allows local users to cause a denial of service (incorrect free operations and system crash) via an open system call.

From the Ubuntu security team

A bug was discovered in the handling of pathname components when used with an autofs direct mount. A local user could exploit this flaw to cause a denial of service (system crash) via an open system call.
