A vulnerability has been discovered in Adobe Reader, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error within CoolType.dll when processing the "uniqueName" entry of SING tables in fonts and can be exploited to cause a stack-based buffer overflow by e.g. tricking a user into opening a malicious PDF file containing a specially crafted embedded font.

The vulnerability is confirmed in versions 8.2.4 and 9.3.4. Other versions may also be affected.

NOTE: The vulnerability is currently being actively exploited.
