Title: JPEG library: Denial of Service
Date: June 11, 2006
Bugs: #130889
ID: 200606-11

---

Synopsis

The JPEG library is vulnerable to a Denial of Service.

Background

The JPEG library is able to load, handle and manipulate images in the
JPEG format.

Affected packages

-------------------------------------------------------------------
 Package          /  Vulnerable  /                      Unaffected
-------------------------------------------------------------------

1 media-libs/jpeg < 6b-r7 >= 6b-r7

Description

Tavis Ormandy of the Gentoo Linux Auditing Team discovered that the
vulnerable JPEG library ebuilds compile JPEG without the --maxmem
feature which is not recommended.

Impact

By enticing a user to load a specially crafted JPEG image file an
attacker could cause a Denial of Service, due to memory exhaustion.

Workaround

There is no known workaround at this time.

Resolution

JPEG users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/jpeg-6b-r7"
