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. Upstream bug report: [1] https://savannah.nongnu.org/bugs/?35603 Upstream patch: [2] http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=c776fc17bfeaa607405fc96620e9445e7a0965c3 Acknowledgements: Red Hat would like to thank Mateusz Jurczyk of the Google Security Team for reporting this issue.
