|Gentoo Linux Security Advisory
Title: ZNC: Directory traversal (GLSA 200909-17)
Date: September 13, 2009
A directory traversal was found in ZNC, allowing for overwriting of
ZNC is an advanced IRC bouncer.
Vulnerable: < 0.074
Unaffected: >= 0.074
Architectures: All supported architectures
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"
