"Drew Yao discovered several vulnerabilities in Ruby which lead to
integer overflows. If a user or automated system were tricked into
running a malicious script, an attacker could cause a denial of
service or execute arbitrary code with the privileges of the user
invoking the program. (CVE-2008-2662, CVE-2008-2663, CVE-2008-2725,
CVE-2008-2726)

Drew Yao discovered that Ruby did not sanitize its input when using
ALLOCA. If a user or automated system were tricked into running a
malicious script, an attacker could cause a denial of service via
memory corruption. (CVE-2008-2664).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
