Medium Nessus Plugin ID 61675


The remote FreeBSD host is missing one or more security-related updates.


SquidClamav developers report :

Add a workaround for a squidGuard bug that unescape the URL and send it back unescaped. This result in garbage staying into pipe of the system command call and could crash squidclamav on next read or return false information. This is specially true with URL containing the %0D or %0A character.

This vulnerability can be triggered only in configurations where external chained URL checker is configured via 'squidguard' directive.


Update the affected packages.
