user-assisted attackers to execute arbitrary code.

<background>
<p>
XEmacs is a highly extensible and customizable text editor.

<description>
<p>
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.
</p>
</description>
<impact type="normal">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All XEmacs users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-editors/xemacs-21.4.22-r1"</code>
<p>
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.
