This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

A vulnerability has been found and corrected in ruby :

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 (CVE-2011-4815).

The updated packages have been patched to correct this issue.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:C)
CVSS Temporal Score : 6.8
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
