Detail

Synopsis

A directory traversal was found in ZNC, allowing for overwriting of arbitrary files.

Background

ZNC is an advanced IRC bouncer.

Description

The vendor reported a directory traversal vulnerability when processing DCC SEND requests.

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All ZNC users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose =net-irc/znc-0.074
