Severity: High Title: SquirrelMail G/PGP plugin: Arbitrary code execution Date: August 11, 2007 Bugs: #185010 ID: 200708-08
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis ========
Multiple vulnerabilities have been discovered in SquirrelMail, allowing for the remote execution of arbitrary code.
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"
