JPEG library: Denial of service — GLSA 200606-11

The JPEG library is vulnerable to a Denial of Service.

Affected packages

Package	media-libs/jpeg on all architectures
Affected versions	< 6b-r7
Unaffected versions	>= 6b-r7

Background

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"
