http://security.gentoo.org/

Severity:	normal
Title:	FreeType: Arbitrary code execution
Date:	08/09/2014
Bugs:	#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	Vulnerable	Unaffected	Architecture(s)
media-libs/freetype	< 2.5.3-r1	>= 2.5.3-r1	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:

      # 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.
