"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."
