CVE-2014-9660: Null Pointer Dereference

First published: Sun Feb 08 2015(Updated: )

The _bdf_parse_glyphs function in bdf/bdflib.c in FreeType before 2.5.4 does not properly handle a missing ENDCHAR record, which allows remote attackers to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted BDF font.
