Jan Lieskovsky from the Red Hat Security Response Team discovered the
|
|
following vulnerabilities in Ghostscript's ICC Library:
|
|
</p>
|
|
<ul>
|
|
<li>Multiple integer overflows (CVE-2009-0583).</li>
|
|
<li>Multiple
|
|
insufficient bounds checks on certain variable sizes
|
|
(CVE-2009-0584).</li>
|
|
</ul>
|
|

<impact type="normal">
|
|
<p>
|
|
A remote attacker could entice a user to open a specially crafted
|
|
PostScript file containing images and a malicious ICC profile, possibly
|
|
resulting in the execution of arbitrary code with the privileges of the
|
|
user running the application.
|

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

All GPL Ghostscript users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/ghostscript-gpl-8.64-r2"</code>
|
|
<p>
|
|
All GNU Ghostscript users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/ghostscript-gnu-8.62.0"</code>
|
|
<p>
|
|
We recommend that users unmerge ESP Ghostscript and use GPL or GNU
|
|
Ghostscript instead:
|
|
</p>
|
|
<code>
|
|
# emerge --unmerge "app-text/ghostscript-esp"</code>
|
|
<p>
|
|
For installation instructions, see above.
