VERIFY ADVISORY:
http://secunia.com/advisories/14411/

CRITICAL:
Less critical

IMPACT:
DoS

WHERE:
>From remote

SOFTWARE:
WU-FTPD 2.x
http://secunia.com/product/1424/

DESCRIPTION:
Adam Zabrocki has reported a vulnerability in WU-FTPD, which can be
exploited by malicious users to cause a DoS (Denial of Service).

The vulnerability is caused due to an error in the handling of "ls"
queries with multiple wildcard chars (*). This causes WU-FTPD to
consume large amounts of CPU resources and may cause the system to
become unresponsive by issuing multiple queries simultaneously.

The vulnerability has been reported in versions 2.6.1 and 2.6.2.
Prior versions may also be affected.

SOLUTION:
Do not grant access to untrusted users.

PROVIDED AND/OR DISCOVERED BY:
