SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200909-17 (ZNC: Directory traversal)
The vendor reported a directory traversal vulnerability when processing DCC SEND requests.
A remote, authenticated user could send a specially crafted DCC SEND request to overwrite arbitrary files with the privileges of the user running ZNC, and possibly cause the execution of arbitrary code e.g. by uploading a malicious ZNC module.
There is no known workaround at this time.
SolutionAll ZNC users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-irc/znc-0.074'
