Gentoo Linux Security Advisory

Title: OptiPNG: User-assisted execution of arbitrary code (GLSA 200903-12)
Severity: normal
Exploitable: remote
Date: March 09, 2009
Bug(s): #260265
ID: 200903-12

Synopsis

A vulnerability in OptiPNG might result in user-assisted execution of arbitrary code.

Background

OptiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information.

Affected Packages

Package: media-gfx/optipng
Vulnerable: < 0.6.2-r1
Unaffected: >= 0.6.2-r1
Architectures: All supported architectures


Description

Roy Tam reported a use-after-free vulnerability in the GIFReadNextExtension() function in lib/pngxtern/gif/gifread.c leading to a memory corruption when reading a GIF image.

Impact

A remote attacker could entice a user to process a specially crafted GIF image, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All OptiPNG users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/optipng-0.6.2-r1"
