Description Vincent Danen 2010-07-09 17:01:51 EDT
Robert Swiecki reported an integer overflow flaw in freetype with how it processes certain fonts.  This could cause applications linked against freetype to crash or, possibly, lead to the execution of arbitrary code if an attacker were able to get a victim to load a malicious font file.

The code in question goes back to the version of freetype in Red Hat Enterprise Linux 3, and can only be triggered when MALLOC_CHECK_=3 is set.

This issue has been given the name CVE-2010-2500.
