GLSA-200703-01 : Snort: Remote execution of arbitrary code

This script is Copyright (C) 2007-2015 Tenable Network Security, Inc.

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200703-01
(Snort: Remote execution of arbitrary code)

The Snort DCE/RPC preprocessor does not properly reassemble certain
types of fragmented SMB and DCE/RPC packets.

Impact :

A remote attacker could send specially crafted fragmented SMB or
DCE/RPC packets, without the need to finish the TCP handshake, that
would trigger a stack-based buffer overflow while being reassembled.
This could lead to the execution of arbitrary code with the permissions
of the user running the Snort preprocessor.

Workaround :

Disable the DCE/RPC processor by commenting the 'preprocessor dcerpc'
section in /etc/snort/snort.conf .

Solution :

All Snort users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-analyzer/snort-'

Risk factor :

Critical / CVSS Base Score : 10.0
Public Exploit Available : true
