SquirrelMail is a webmail package written in PHP. It supports IMAP and
|
|
SMTP protocols.

<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>

|
<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 ">=mail-client/squirrelmail-1.4.10a-r2"</code>
|
