Description:
A vulnerability has been reported in WU-FTPD, which potentially can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the S/KEY challenge handling. This can be exploited by supplying overly long, specially crafted user credentials, which causes a buffer overflow and may allow execution of arbitrary code.
Successful exploitation requires that S/KEY authentication has been enabled.
The vulnerability was originally reported in version 2.6.0 in June 2000, but has now also been reported to affect the latest version (2.6.2).
