SquirrelMail: CSRF in the empty trash feature and in Index Order page

Multiple cross-site request forgery (CSRF) vulnerabilities in SquirrelMail 1.4.21 and earlier allow remote attackers to hijack the authentication of unspecified victims via vectors involving (1) the empty trash implementation and (2) the Index Order (aka options_order) page, a different issue than CVE-2010-4555.

squirrelmail: not fixed in RHSA-2012:0103

functions/imap_general.php in SquirrelMail, as used in Red Hat Enterprise Linux (RHEL) 4 and 5, does not properly handle 8-bit characters in passwords, which allows remote attackers to cause a denial of service (disk consumption) by making many IMAP login attempts with different usernames, leading to the creation of many preference files. NOTE: this issue exists because of an incorrect fix for CVE-2010-2813.

SquirrelMail: DoS (disk space consumption) by random IMAP login attempts with 8-bit characters in the password

functions/imap_general.php in SquirrelMail before 1.4.21 does not properly handle 8-bit characters in passwords, which allows remote attackers to cause a denial of service (disk consumption) by making many IMAP login attempts with different usernames, leading to the creation of many preferences files.

SquirrelMail: Mail Fetch plugin -- port-scans via non-standard POP3 server ports

The Mail Fetch plugin in SquirrelMail 1.4.20 and earlier allows remote authenticated users to bypass firewall restrictions and use SquirrelMail as a proxy to scan internal networks via a modified POP3 port number.

squirrelmail: use of unserialize function for the attachments value in compose.php

compose.php in SquirrelMail 1.4.22 calls unserialize for the $attachments value, which originates from an HTTP POST request. NOTE: the vendor disputes this because these two conditions for PHP object injection are not satisfied: existence of a PHP magic method (such as __wakeup or __destruct), and any attack-relevant classes must be declared before unserialize is called (or must be autoloaded).

squirrelmail: use of unserialize function for the mailtodata value in compose.php

compose.php in SquirrelMail 1.4.22 calls unserialize for the $mailtodata value, which originates from an HTTP GET request. This is related to mailto.php.

squirrelmail: improper handling of RCDATA and RAWTEXT type elements causing XSS

XSS was discovered in SquirrelMail through 1.4.22 and 1.5.x through 1.5.2. Due to improper handling of RCDATA and RAWTEXT type elements, the built-in sanitization mechanism can be bypassed. Malicious script content from HTML e-mail can be executed within the application context via crafted use of (for example) a NOEMBED, NOFRAMES, NOSCRIPT, or TEXTAREA element.

SquirrelMail: Directory traversal flaw in Deliver.class.php can allow a remote attacker to retrieve or delete arbitrary files
