ZNC is an advanced IRC bouncer.
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.
All ZNC users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/znc-0.074"
