GLSA-200707-06 : XnView: Stack-based buffer overflow

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200707-06
(XnView: Stack-based buffer overflow)

XnView is vulnerable to a stack-based buffer overflow while processing
an XPM file with an overly long section string (greater than 1024
bytes).

Impact :

An attacker could entice a user to view a specially crafted XPM file
with XnView that could trigger the vulnerability and possibly execute
arbitrary code with the rights of the user running XnView.

Workaround :

There is no known workaround at this time.

Solution :

No update appears to be forthcoming from the XnView developer and
XnView is proprietary, so the XnView package has been masked in
Portage. We recommend that users select an alternate graphics viewer
and conversion utility, and unmerge XnView:
# emerge --unmerge xnview

Risk factor :

Critical / CVSS Base Score : 10.0
