GLSA-200708-08 : SquirrelMail G/PGP plugin: Arbitrary code execution

high Nessus Plugin ID 25873

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200708-08 (SquirrelMail G/PGP plugin: Arbitrary code execution)

 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.
 Impact :

 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.
 Workaround :

 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.

Solution

All SquirrelMail users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=mail-client/squirrelmail-1.4.10a-r2'
