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

Medium Nessus Plugin ID 63603


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


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.

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.


Update the affected packages.
