Debian DLA-1427-1 : znc security update

High Nessus Plugin ID 111085


The remote Debian host is missing a security update.


It was discovered that there were two issues in znc, a modular IRC bouncer :

- There was insufficient validation of lines coming from the network allowing a non-admin user to escalate his privilege and inject rogue values into znc.conf.

- A path traversal vulnerability (via '../' being embedded in a web skin name) to access files outside of the allowed directory. (CVE-2018-14056)

For Debian 8 'Jessie', these issues have been fixed in znc version 1.4-2+deb8u1.

We recommend that you upgrade your znc packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Upgrade the affected packages.
