Common Vulnerabilities and Exposures assigned an identifier CVE-2012-4190 to
the following vulnerability:

Name: CVE-2012-4190
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-4190
Assigned: 20120808
Reference: http://www.mozilla.org/security/announce/2012/mfsa2012-88.html

The FT2FontEntry::CreateFontEntry function in FreeType, as used in the
Android build of Mozilla Firefox before 16.0.1 on CyanogenMod 10,
allows remote attackers to cause a denial of service (memory
corruption and application crash) or possibly execute arbitrary code
via unspecified vectors.


NOTE: the upstream bug is still private, so no further details are currently available as to whether or not this affects FreeType (or if it just affects the Firefox on Android usage and/or implementation of FreeType).

I read the upstream bug in full.  It doesn't affect FreeType, or any other code we're interested in.
