"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."
