Description David Walser 2013-08-19 23:30:16 CEST
Fedora has issued an advisory on August 2:

Mageia 2 is not affected, as only version 1.0 of znc is affected.

Patched packages uploaded for Mageia 3 and Cauldron.


Updated znc packages fix security vulnerability:

Multiple vulnerabilities were reported in ZNC version 1.0 which can be exploited
by malicious authenticated users to cause a denial of service. These flaws are
due to errors when handling the "editnetwork", "editchan", "addchan", and
"delchan" page requests; they can be exploited to cause a NULL pointer
dereference (CVE-2013-2130).


Updated packages in core/updates_testing:

from znc-1.0-2.1.mga3.src.rpm


Steps to Reproduce:
Comment 1 claire robinson 2013-08-20 16:05:42 CEST
Testing complete mga3 64

No PoC's but the CVE is to do with the webadmin interface so checking that works.

$ znc --makeconf

answer all the questions it asks and allow it to start.

created with user/password  znctest/znctest

Connected to the running znc instance with an irc client with the server as localhost and the port znc was configured to listen on (I used 3456) and the server password set to znctest/freenode:znctest

Logged into the web interface at https://localhost:3456 and made sure it was still able to edit channels and networks.

Killed znc with 'killall znc'

It does seem to be missing a systemd service so i'll create a new bug for that.
