Background ========== Courier is an integrated mail and groupware server based on open protocols. It provides ESMTP, IMAP, POP3, webmail, and mailing list services within a single framework. The webmail functionality included in Courier called SqWebMail allows you to access mailboxes from a web browser. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-mta/courier <= 0.45.6 >= 0.45.6.20040618 Description =========== Luca Legato found that SqWebMail is vulnerable to a cross-site scripting (XSS) attack. An XSS attack allows an attacker to insert malicious code into a web-based application. SqWebMail doesn't filter appropriately data coming from message headers before displaying them. Impact ====== By sending a carefully crafted message, an attacker can inject and execute script code in the victim's browser window. This allows to modify the behaviour of the SqWebMail application, and/or leak session information such as cookies to the attacker. Workaround ========== There is no known workaround at this time. All users are encouraged to upgrade to the latest available version of Courier. Resolution ========== All Courier users should upgrade to the latest version: # emerge sync # emerge -pv ">=mail-mta/courier-0.45.6.20040618" # emerge ">=mail-mta/courier-0.45.6.20040618" References ========== [ 1 ] CAN-2004-0591 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0591 [ 2 ] XSS definition http://www.cert.org/advisories/CA-2000-02.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200408-02.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.
