"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)"
