Adobe Flash Player JPG Processing Heap Overflow Vulnerability
------------------------------------------------------------------------

SUMMARY

A vulnerability allows remote attackers to execute arbitrary code on
systems with vulnerable installations of the Adobe Flash Player. User
interaction is required to exploit this vulnerability in that the target
must visit a malicious page or open a malicious file.

DETAILS

The specific flaw exists in the Flash Player's parsing of JPG images
embedded in SWF files. The Flash Player trusts the signed X and Y
densities specified in the JPG header and makes memory allocations
accordingly. A processing loop later treats these values as unsigned,
leading to excessive loop iterations and heap corruption while decoding
the rest of the image.
