Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
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.
