Synopsis :

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

Description :

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.
