# Stack-based buffer overflow in CoolType.dll in Adobe Reader and Acrobat 9.x before 9.4, and 8.x before 8.2.5 on…

Adobe Acrobat and Reader contain a stack-based buffer overflow in how they handle crafted PDF files. A remote attacker can execute code on the machine that opens the file, or crash the reader.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Stack-based buffer overflow in CoolType.dll in Adobe Reader and Acrobat 9.x before 9.4, and 8.x before 8.2.5 on Windows and Mac OS X, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a PDF document with a long field in a Smart INdependent Glyphlets (SING) table in a TTF font, as exploited in the wild in September 2010. NOTE: some of these details are obtained from third party information.
