Synopsis :

The remote Amazon Linux AMI host is missing a security update.

Description :

Ruby (aka CRuby) before 1.8.7-p357 computes hash values without
restricting the ability to trigger hash collisions predictably, which
allows context-dependent attackers to cause a denial of service (CPU
consumption) via crafted input to an application that maintains a hash
table.
