Vigil@nce - Linux kernel: denial of service via ISOFS
August 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
A local attacker can mount a malicious ISOFS image on the Linux kernel, in order to trigger a denial of service.
Impacted products: Linux
Creation date: 26/08/2014
DESCRIPTION OF THE VULNERABILITY
An ISOFS image contains a filesystem, which can be mounted by the Linux kernel.
However, when the ISOFS image relocates a directory, an infinite recursion occurs in the parse_rock_ridge_inode_internal() function.
A local attacker can therefore mount a malicious ISOFS image on the Linux kernel, in order to trigger a denial of service.
