Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
eEye Digital Security has been reported a vulnerability in Microsoft Windows DirectShow, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a validation error in QUARTZ.DLL when decoding AVI movie files. This can be exploited to write a null byte to an arbitrary memory location e.g. the header of the heap block.

Successful exploitation allows arbitrary code execution, but requires that the user open a malicious AVI file with specially crafted value in the length field of the "strn" element.
