medium Nessus Plugin ID 61503

Synopsis

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

Description

The libcloud development team reports :

When establishing a secure (SSL / TLS) connection to a target server an invalid regular expression has been used for performing the hostname verification.

For example, certificate with a hostname field of 'aexample.com' was considered a valid certificate for domain 'example.com'.
