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)
