GLSA 200606-11: JPEG library: Denial of Service

Severity:normal
Title:JPEG library: Denial of Service
Date:06/11/2006
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 Architecture(s)
media-libs/jpeg < 6b-r7 >= 6b-r7 All supported architectures

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"
