Description

The remote host is affected by the vulnerability described in GLSA-201101-06 (IO::Socket::SSL: Certificate validation error)

The vendor reported that IO::Socket::SSL does not properly handle     Common Name (CN) fields.

Impact :

A remote attacker might employ a specially crafted certificate to     conduct man-in-the-middle attacks on SSL connections made using     IO::Socket::SSL.

Workaround :

There is no known workaround at this time.
