Synopsis: Moderate: ruby security and bug fix update
Issue Date: 2013-01-08
CVE Numbers: CVE-2012-4481
 CVE-2012-4522
--

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.
