CVE-2012-1130 freetype: heap buffer over-read in PCF parser pcf_get_properties() (#35603)
Last modified: 2016-11-08 10:52:31 EST
An out-of heap-based buffer read flaw was found in the way FreeType font rendering engine retrieved properties information from Portable Compiled Format (PCF) bitmap font files. A remote attacker could provide a specially-crafted PCF font file, which once opened in an application linked against FreeType would lead to that application crash.
