Synopsis
========
Multiple integer overflow errors in XEmacs might allow remote,
user-assisted attackers to execute arbitrary code.
Background
==========
XEmacs is a highly extensible and customizable text editor.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-editors/xemacs < 21.4.22-r1 >= 21.4.22-r1
Description
===========
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.
Resolution
==========
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.
