1. Problem Description
The wu-ftp FTP server does not do proper bounds checking while
processing the SITE EXEC command.
2. Impact
An remote attacker could execute arbitrary machine code as root
on a FTP server using wu-ftpd.
This bug could only be exploited if anonymous access to the FTP
server is allowed.
3. Solution
We recommend using our audited 2.4er version of wu-ftpd.
Update the package from our FTP server.
Please verify these md5 checksums of the updates before
installing: (For SuSE 6.0, please use the 6.1 updates)
