Summary
Red Hat Security Advisory: : Updated wu-ftpd packages fix remote vulnerability.

Notes

Topic
Updated wu-ftpd packages are now available that fix a remotely exploitable security issue.
Details
The wu-ftpd package contains the Washington University FTP (File Transfer Protocol) server daemon. FTP is a method of transferring files between computers on a network. 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 Linux 7.1 and 7.2 contain a version of wu-ftpd that is affected by this bug, although it is believed this issue will not be remotely exploitable due to compiler padding of the buffer targeted for the overflow. Red Hat Linux 7.3 and 8.0 contain a version of wu-ftpd that is remotely exploitable. Red Hat advises all users of wu-ftpd to upgrade to these erratum packages, which contain a security patch and is not vulnerable to this issue. Red Hat would like to thank Wojciech Purczynski and Janusz Niewiadomski of ISEC Security Research for their responsible disclosure of this issue.
