CVE-2010-3311: Buffer Overflow
Integer overflow in base/ftstream.c in libXft (aka the X FreeType library) in FreeType before 2.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted Compact Font Format (CFF) font file that triggers a heap-based buffer overflow, related to an "input stream position error" issue, a different vulnerability than CVE-2010-1797.
Other sources
Marc Schoenefeld found an input stream position error in the way FreeType font rendering engine processed input file streams. If a user loaded a specially-crafted font file with an application linked against FreeType and relevant font glyphs were subsequently rendered with the X FreeType library (libXft), it could cause the application to crash or, possibly execute arbitrary code (integer overflow leading to heap-based buffer overflow in the libXft library) with the privileges of the user running the application. Different vulnerability than CVE-2010-1797.
Affected versions: freetype-2.3 and before that. Latest upstream version (2.4) is not affected
