Synopsis :

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

Description :

Ruby developers report :

Unrestricted entity expansion can lead to a DoS vulnerability in
REXML. (The CVE identifier will be assigned later.) We strongly
recommend to upgrade ruby.

When reading text nodes from an XML document, the REXML parser can be
coerced in to allocating extremely large string objects which can
consume all of the memory on a machine, causing a denial of service.
