Gentoo Linux Security Advisory

Title: libjpeg-turbo: User-assisted execution of arbitrary code (GLSA 201209-13)
Severity: normal
Exploitable: remote
Date: September 26, 2012
Bug(s): #426938
ID: 201209-13

Synopsis

A vulnerability in libjpeg-turbo could result in execution of
arbitrary code or Denial of Service.


Background

libjpeg-turbo accelerates JPEG compression and decompression.

Affected Packages

Package: media-libs/libjpeg-turbo
Vulnerable: < 1.2.1
Unaffected: >= 1.2.1
Architectures: All supported architectures


Description

A vulnerability in the get_sos() function in jdmarker.c could cause a
heap-based buffer overflow.


Impact

A remote attacker could entice a user to open a specially crafted JPEG
file in an application linked against libjpeg-turbo, possibly resulting
in the remote execution of arbitrary code with the permissions of the
user running the application, or Denial of Service.


Workaround

There is no known workaround at this time.

Resolution

All libjpeg-turbo users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=media-libs/libjpeg-turbo-1.2.1"
   
Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these packages.
