Resumen:	The remote host is missing an update for the 'ruby'; package(s) announced via the referenced advisory.
Descripción:	Summary: The remote host is missing an update for the 'ruby' package(s) announced via the referenced advisory. Vulnerability Insight: Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to do system management tasks. A flaw was found in the way large amounts of memory were allocated on 64-bit systems when using the BigDecimal class. A context-dependent attacker could use this flaw to cause memory corruption, causing a Ruby application that uses the BigDecimal class to crash or, possibly, execute arbitrary code. This issue did not affect 32-bit systems. (CVE-2011-0188) A race condition flaw was found in the remove system entries method in the FileUtils module. If a local user ran a Ruby script that uses this method, a local attacker could use this flaw to delete arbitrary files and directories accessible to that user via a symbolic link attack. (CVE-2011-1004) A flaw was found 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-2011-1005) Red Hat would like to thank Drew Yao of Apple Product Security for reporting the CVE-2011-0188 issue. All Ruby users should upgrade to these updated packages, which contain backported patches to resolve these issues. Affected Software/OS: ruby on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6), Red Hat Enterprise Linux Workstation (v. 6) Solution: Please Install the Updated Packages. CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
