from PostScript and PDF files.

An attacker could craft a malicious PostScript file and entice a user
to run pstotext on it, resulting in the execution of arbitrary commands
with the permissions of the user running pstotext.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>

# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=app-text/pstotext-1.8g-r1"</code>
