Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Mitre reports :

ZNC before 1.7.1-rc1 does not properly validate untrusted lines coming from the network, allowing a non-admin user to escalate his privilege and inject rogue values into znc.conf.

ZNC before 1.7.1-rc1 is prone to a path traversal flaw via ../ in a web skin name to access files outside of the intended skins directories.

Solution

Update the affected package.
