Gentoo Linux Security Advisory
Title: ZNC: Directory traversal (GLSA 200909-17)
Severity: normal
Exploitable: remote
Date: September 13, 2009
Bug(s): #278684
ID: 200909-17
Synopsis
A directory traversal was found in ZNC, allowing for overwriting of
arbitrary files.
Background
ZNC is an advanced IRC bouncer.
Affected Packages
Package: net-irc/znc
Vulnerable: < 0.074
Unaffected: >= 0.074
Architectures: All supported architectures
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:
Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/znc-0.074" |
