Background ========== SquirrelMail is a webmail package written in PHP. It supports IMAP and SMTP protocols. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-client/squirrelmail < 1.4.10a-r2 >= 1.4.10a-r2 Description =========== 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. Resolution ========== All SquirrelMail users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.10a-r2" References ========== [ 1 ] CVE-2005-1924 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-1924 [ 2 ] CVE-2006-4169 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4169 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200708-08.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
