iDEFENSE has discovered a vulnerability in the Linux kernel, which can be exploited by malicious, local users to gain escalated privileges on a vulnerable system.
The vulnerability is caused due to a boundary error within the ISO9660 ("isofs") file system component when handling symbolic links. This can be exploited to cause a buffer overflow via an overly long symbolic link on e.g. a mounted CDROM.
Successful exploitation may allow arbitrary code execution with root or kernel level privileges.
The vulnerability reportedly affects the 2.4.x, 2.5.x, and 2.6.x kernel branches.
Solution: Update to Linux kernel versions 2.4.26 and 2.6.6-rc1.
