CERT appears to have left out wu-ftpd-2.6.0 (although they included it in
the lists for the other two vulnerabilities).

Version 2.6.0 does *not* have the "MAPPING_CHDIR Buffer Overflow"
vulnerability, at least if the ANNOUNCE-RELEASE file for that version is
to be believed.  It reads, in part:

"Corrected an error in the MAPPING_CHDIR feature which could be used to
gain root privileges on the server."

Presumably, this refers to this vulnerability.
