Shockwave-SA-10/29/2010: Adobe Shockwave Player – Chunk Parsing Vulnerability
Affected Software

* Adobe Shockwave Player

Description of Vulnerability

Secunia Research has discovered a vulnerability in Adobe Shockwave
Player, which may be exploited by malicious people to compromise a
user’s system.

The vulnerability is caused by a logic error in TextXtra.x32 when
parsing “DEMX” chunks. This can be exploited to cause a heap-based
buffer overflow via a specially crafted Director file as a function
does not reallocate a buffer to contain a section of data as expected,
but another function to still copy chunk data into the insufficiently
sized buffer.

Successful exploitation allows execution of arbitrary code.
