CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:N/C:P/I:P/A:P

Summary:
The remote host is missing an update for the 'ruby' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
ruby on CentOS 5

Technical Details:
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) It was found that WEBrick (the Ruby HTTP server toolkit) did not filter terminal escape sequences from its log files. A remote attacker could use specially-crafted HTTP requests to inject terminal escape sequences into the WEBrick log files. If a victim viewed the log files with a terminal emulator, it could result in control characters being executed with the privileges of that user. (CVE-2009-4492) A cross-site scripting (XSS) flaw was found in the way WEBrick displayed error pages. A remote attacker could use this flaw to perform a cross-site scripting attack against victims by tricking them into visiting a specially-crafted URL. (CVE-2010-0541) 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 and CVE-2010-0541 issues. All Ruby users should upgrade to these updated Linux Distribution Packages, which contain backported patches to resolve these issues.

Recommendations:
Please install the updated Linux Distribution Packages.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
