Gentoo Linux Security Advisory

Title: FreeType: Arbitrary code execution (GLSA 201408-02)
Severity: normal
Exploitable: remote
Date: August 09, 2014
Bug(s): #504088
ID: 201408-02

Synopsis

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


Background

FreeType is a high-quality and portable font engine.

Affected Packages

Package: media-libs/freetype
Vulnerable: < 2.5.3-r1
Unaffected: >= 2.5.3-r1
Architectures: All supported architectures


Description

A stack-based buffer overflow exists in Freetype’s cf2_hintmap_build
function in cff/cf2hints.c.


Impact

A remote attacker may be able to execute arbitrary code or cause a
Denial of Service condition via specially crafted font file.


Workaround

There is no known workaround at this time.

Resolution

All FreeType users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=media-libs/freetype-2.5.3-r1"
   
Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.
