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

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.
