+ <title>SquirrelMail G/PGP plugin: Arbitrary code execution</title>
+ <synopsis>
+ Multiple vulnerabilities have been discovered in SquirrelMail, allowing for
+ the remote execution of arbitrary code.

+ <background>
+ <p>
+ SquirrelMail is a webmail package written in PHP. It supports IMAP and
+ SMTP protocols.
+ </p>
+ </background>
+ <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 "&gt;=mail-client/squirrelmail-1.4.10a-r2"</code>
