Description:
Neel Mehta has reported a vulnerability in Snort, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the DCE/RPC preprocessor when reassembling SMB Write AndX requests. This can be exploited to cause a stack-based buffer overflow via a specially crafted packet sent over a network that is monitored by Snort .
Successful exploitation allows execution of arbitrary code.
The vulnerability reportedly affects the following versions:
* Snort 2.6.1, 2.6.1.1, and 2.6.1.2
* Snort 2.7.0 beta 1
Solution:
Update to version 2.6.1.3.
The vendor recommends that beta users disable the DCE/RPC preprocessor.
