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 / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/libjpeg-turbo
< 1.2.1 >= 1.2.1
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:
# 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.
