GLSA-200510-15 : Lynx: Buffer overflow in NNTP processing

This script is Copyright (C) 2005-2015 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-200510-15
(Lynx: Buffer overflow in NNTP processing)

When accessing a NNTP URL, Lynx connects to a NNTP server and
retrieves information about the available articles in the target
newsgroup. Ulf Harnhammar discovered a buffer overflow in a function
that handles the escaping of special characters.

Impact :

An attacker could setup a malicious NNTP server and entice a user
to access it using Lynx (either by creating NNTP links on a web page or
by forcing a redirect for Lynx users). The data returned by the NNTP
server would trigger the buffer overflow and execute arbitrary code
with the rights of the user running Lynx.

Workaround :

There is no known workaround at this time.

Solution :

All Lynx users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=www-client/lynx-2.8.5-r1'

Risk factor :

High / CVSS Base Score : 7.5
