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"
Availability
============
This GLSA and any updates to it are available for viewing at
the Gentoo Security Website:
