Synopsis

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

2.  Impact Information

Background

FreeType is a high-quality and portable font engine.

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.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All FreeType users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync

Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying these packages.
