Ruby is an interpreted scripting language for quick and easy object-oriented programming. 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) Red Hat would like to thank Drew Yao of the Apple Product Security team for reporting these issues. 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) Users of Ruby should upgrade to these updated packages, which contain a backported patches to resolve these issues.
