<p>
SquirrelMail is a webmail package written in PHP. It supports IMAP and
SMTP protocols.

<description>
<p>
The functions deletekey(), gpg_check_sign_pgp_mime() and gpg_recv_key()
used in the SquirrelMail G/PGP encryption plugin do not properly escape
user-supplied data.
</p>
</description>
<impact type="high">
<p>
An authenticated user could use the plugin to execute arbitrary code on
the server, or a remote attacker could send a specially crafted e-mail
to a SquirrelMail user, possibly leading to the execution of arbitrary
code with the privileges of the user running the underlying web server.
Note that the G/PGP plugin is disabled by default.
</p>
</impact>
<workaround>
<p>
Enter the SquirrelMail configuration directory
(/usr/share/webapps/squirrelmail/version/htdocs/config), then execute
the conf.pl script. Select the plugins menu, then select the gpg plugin
item number in the "Installed Plugins" list to disable it. Press S to
save your changes, then Q to quit.
</p>
</workaround>
<resolution>
<p>
All SquirrelMail users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=mail-client/squirrelmail-1.4.10a-r2&quot;</code>
</resolution>
