Description

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.
