Gentoo Linux Security Advisory

Title: Netpbm: User-assisted arbitrary code execution (GLSA 201311-08)
Severity: normal
Exploitable: remote
Date: November 13, 2013
Bug(s): #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: media-libs/netpbm
Vulnerable: < 10.49.00
Unaffected: >= 10.49.00
Architectures: 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:
Code:
# 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.
