"This ruby update improves return value checks for openssl function
OCSP_basic_verify() (CVE-2009-0642) which allowed an attacker to use
revoked certificates. The entropy of DNS identifiers was increased
(CVE-2008-3905) to avaid spoofing attacks. The code for parsing XML
data was vulnerable to a denial of service bug (CVE-2008-3790). An
attack on algorithm complexity was possible in function
WEBrick::HTTP::DefaultFileHandler() while parsing HTTP requests
(CVE-2008-3656) as well as by using the regex engine (CVE-2008-3443)
causing high CPU load. Ruby's access restriction code (CVE-2008-3655)
as well as safe-level handling using function DL.dlopen()
(CVE-2008-3657) and big decimal handling (CVE-2009-1904) was improved.
Bypassing HTTP basic authentication (authenticate_with_http_digest) is
not possible anymore."
