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)
