4) 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 function in dirapi.dll not validating
the size and number of sub-chunks inside a "pamm" chunk during initial
parsing of the sub-chunks. This can be exploited to corrupt memory
outside the bounds of a buffer allocated for the "pamm" data via a
specially crafted Director file.
Successful exploitation may allow execution of arbitrary code.
