Resumen:	The remote host is missing an update for the 'ruby' package(s) announced via the ALAS-2012-35 advisory.
Descripción:	Summary: The remote host is missing an update for the 'ruby' package(s) announced via the ALAS-2012-35 advisory. Vulnerability Insight: 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. Affected Software/OS: 'ruby' package(s) on Amazon Linux. Solution: Please install the updated package(s). CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
