CVE-2012-1126 freetype: heap buffer over-read in BDF parsing _bdf_is_atom() (#35597, #35598)
Last modified: 2016-11-08 11:20:04 EST
An out-of heap-based buffer read flaw was found in the way FreeType font rendering engine performed:
1) adding of properties,
2) parsing of properties,
3) checking if particular property is an atom
for Glyph bitmap distribution format (BDF) fonts. A remote attacker could provide a specially-crafted BDF font file, which once processed in an application linked against FreeType would lead to that application crash.
