GLSA-201006-15 : XEmacs: User-assisted execution of arbitrary code

This script is Copyright (C) 2010-2014 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-201006-15
(XEmacs: User-assisted execution of arbitrary code)

Tielei Wang reported multiple integer overflow vulnerabilities in the
tiff_instantiate(), png_instantiate() and jpeg_instantiate() functions
in glyphs-eimage.c, all possibly leading to heap-based buffer
overflows.

Impact :

A remote attacker could entice a user to open a specially crafted TIFF,
JPEG or PNG file using XEmacs, possibly resulting in the remote
execution of arbitrary code with the privileges of the user running the
application, or a Denial of Service condition.

Workaround :

There is no known workaround at this time.

Solution :

All XEmacs users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-editors/xemacs-21.4.22-r1'
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since July 26, 2009. It is likely that your system is already
no longer affected by this issue.

Risk factor :

Critical / CVSS Base Score : 10.0
