Description

No CVE yet, one has been requested. Upgrade to 0.072 of ZNC, fixes security issue in bug 513152 An users data directory traversal flaw was found in the way ZNC used to handle file upload requests via Direct Client Connection (DCC) /dcc SEND messages. A remote IRC user could issue a /dcc SEND message with a specially crafted content (file to upload), which once accepted by a local, unsuspecting ZNC user, would overwrite relevant files in the users/<user>/downloads data directory.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
