Synopsis

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

2.  Impact Information

Background

FreeType is a portable font engine.

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.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All FreeType users should upgrade to the latest stable version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/freetype-2.1.10-r2"
