http://security.gentoo.org/

Severity:	normal
Title:	Netpbm: User-assisted arbitrary code execution
Date:	11/13/2013
Bugs:	#308025
ID:	201311-08

Synopsis

A vulnerability in Netpbm could result in execution of arbitrary code or Denial of Service.

Background

Netpbm is a toolkit for manipulation of graphic images, including conversion of images between a variety of different formats.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/netpbm	< 10.49.00	>= 10.49.00	All supported architectures

Description

A stack-based buffer overflow exists in converter/ppm/xpmtoppm.c in Netpbm.

Impact

A remote attacker could entice a user to open a specially crafted XMP file using Netpbm, possibly resulting in execution of arbitrary code with the privileges of the process, or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All Netpbm users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=media-libs/netpbm-10.49.00"

Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
