FreeBSD : squid -- confusing results on empty acl declarations (a30e5e44-5440-11d9-9e1e-c296ac722cb3)

critical Nessus Plugin ID 19054

Synopsis

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

Description

Applying an empty ACL list results in unexpected behavior : anything will match an empty ACL list. For example,

The meaning of the configuration gets very confusing when we encounter empty ACLs such as

acl something src '/path/to/empty_file.txt' http_access allow something somewhere

gets parsed (with warnings) as

http_access allow somewhere

And similarily if you are using proxy_auth acls without having any auth schemes defined.

Solution

Update the affected package.
