Synopsis

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

2.  Impact Information

Background

libjpeg-turbo accelerates JPEG compression and decompression.

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.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All libjpeg-turbo users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # 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.
