CVE-2012-1141: Buffer Overflow

First published: Tue Mar 06 2012(Updated: )

An out-of heap-based buffer read flaw was found in the way FreeType font rendering engine performed conversion of ASCII string objects, contained within glyph bitmap distribution format (BDF) font file, into signed short integers. A remote attacker could provide a specially-crafted BDF file, which once processed by an application linked against FreeType would lead to that application crash.
