Gentoo Linux Security Advisory

Title: FreeType: Multiple integer overflows (GLSA 200607-02)
Severity: normal
Exploitable: remote
Date: July 09, 2006
Updated: September 03, 2006
Bug(s): #124828
ID: 200607-02

Synopsis

Multiple remotely exploitable buffer overflows have been discovered in FreeType, resulting in the execution of arbitrary code.

Background

FreeType is a portable font engine.

Affected Packages

Package: media-libs/freetype
Vulnerable: < 2.1.10-r2
Unaffected: >= 2.1.10-r2
Unaffected: < 2.0
Architectures: All supported architectures


Description

Multiple integer overflows exist in a variety of files (bdf/bdflib.c, sfnt/ttcmap.c, cff/cffgload.c, base/ftmac.c).

Impact

A remote attacker could exploit these buffer overflows by enticing a user to load a specially crafted font, which could result in the execution of arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

All FreeType users should upgrade to the latest stable version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/freetype-2.1.10-r2"


References
