Description Jan Lieskovsky 2010-07-26 02:16:26 EDT
A denial of service flaw was found in the way SquirrelMail processed
random login attempts with 8-bit characters in the password. A remote
attacker could use this flaw to cause the server system potentially
to run out of the hard disk space via random login attempts, causing
SquirrelMail temporarily to accept the login and create a preferences
file for the given username.
