- Updated wu-ftpd packages are available that fix an off-by-one buffer
- overflow.
-
- The wu-ftpd package contains the Washington University FTP (File Transfer
- Protocol) server daemon. FTP is a method of transferring files between
- machines.
-
- An off-by-one bug has been discovered in versions of wu-ftpd up to and
- including 2.6.2. On a vulnerable system, a remote attacker would be able
- to exploit this bug to gain root privileges.
-
- Red Hat Enterprise Linux contains a version of wu-ftpd that is affected by
- this bug, although it is believed that this issue will not be remotely
- exploitable due to compiler padding of the buffer that is the target of the
- overflow. However, Red Hat still advises that all users of wu-ftpd upgrade
- to these erratum packages, which contain a security patch.
-
- Red Hat would like to thank Wojciech Purczynski and Janusz Niewiadomski of
- ISEC Security Research for their responsible disclosure of this issue.
