Critical Nessus Plugin ID 60441

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis

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

Description

Multiple integer overflows leading to a heap overflow were discovered in the array- and string-handling code used by Ruby. An attacker could use these flaws to crash a Ruby application or, possibly, execute arbitrary code with the privileges of the Ruby application using untrusted inputs in array or string operations. (CVE-2008-2376, CVE-2008-2663, CVE-2008-2725, CVE-2008-2726)

It was discovered that Ruby used the alloca() memory allocation function in the format (%) method of the String class without properly restricting maximum string length. An attacker could use this flaw to crash a Ruby application or, possibly, execute arbitrary code with the privileges of the Ruby application using long, untrusted strings as format strings. (CVE-2008-2664)

A flaw was discovered in the way Ruby's CGI module handles certain HTTP requests. A remote attacker could send a specially crafted request and cause the Ruby CGI script to enter an infinite loop, possibly causing a denial of service. (CVE-2006-6303)

Solution

Update the affected packages.
