Description Huzaifa S. Sidhpurwala 2012-04-22 07:24:59 UTC

Mateusz Jurczyk of the Google Security Team discovered an off-by-one error in the OpenType Sanitizer using the Address Sanitizer tool. This can lead to an out-of-bounds read and execution of an uninitialized function pointer during parsing and possible remote code execution.
