> 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.
