Insight
A vulnerability has been found and corrected in squirrelmail: 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 (CVE-2010-2813). This update provides squirrelmail 1.4.21, which is not vulnerable to this issue.
