GLSA 201311-08: Netpbm: User-assisted arbitrary code execution

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.
