Vulnerability Name:

CVE-2012-2124 (CCN-81204)

Assigned:2012-04-20
Published:2012-04-20
Updated:2023-02-13
Summary: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.
