Robert Swiecki reported an invalid free flaw, that could possibly corrupt the heap, in freetype. This could cause applications linked against freetype to crash (SIGABRT) 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 affected code is not present in Red Hat Enterprise Linux 3 (freetype 2.1.4). In Red Hat Enterprise Linux 4 and 5 this code is present, but does not cause a crash. This issue has been given the name CVE-2010-2498.
