Background ========== SquirrelMail is a webmail package written in PHP. It supports IMAP and SMTP protocols. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-client/squirrelmail < 1.4.6 >= 1.4.6 Description =========== SquirrelMail does not validate the right_frame parameter in webmail.php, possibly allowing frame replacement or cross-site scripting (CVE-2006-0188). Martijn Brinkers and Scott Hughes discovered that MagicHTML fails to handle certain input correctly, potentially leading to cross-site scripting (only Internet Explorer, CVE-2006-0195). Vicente Aguilera reported that the sqimap_mailbox_select function did not strip newlines from the mailbox or subject parameter, possibly allowing IMAP command injection (CVE-2006-0377). Impact ====== By exploiting the cross-site scripting vulnerabilities, an attacker can execute arbitrary scripts running in the context of the victim's browser. This could lead to a compromise of the user's webmail account, cookie theft, etc. A remote attacker could exploit the IMAP command injection to execute arbitrary IMAP commands on the configured IMAP server. Workaround ========== There is no known workaround at this time. Resolution ========== All SquirrelMail users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.6" Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update.
