Scientific Linux Security Update : ruby on SL5.x i386/x86_64

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was found that certain methods did not sanitize file names before
passing them to lower layer routines in Ruby. If a Ruby application
created files with names based on untrusted input, it could result in
the creation of files with different names than expected.
(CVE-2012-4522)

It was found that the SLSA-2011:0909 update did not correctly fix the
CVE-2011-1005 issue, a flaw in the method for translating an exception
message into a string in the Exception class. A remote attacker could
use this flaw to bypass safe level 4 restrictions, allowing untrusted
(tainted) code to modify arbitrary, trusted (untainted) strings, which
safe level 4 restrictions would otherwise prevent. (CVE-2012-4481)

This update also fixes the following bug :

- Prior to this update, the 'rb_syck_mktime' option could,
under certain circumstances, terminate with a
segmentation fault when installing libraries with
certain gems. This update modifies the underlying code
so that Ruby gems can be installed as expected.
