SuSE 10 Security Update : ruby (ZYPP Patch Number 6338)

This script is Copyright (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

The remote SuSE 10 host is missing a security-related patch.

Description :

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.
