openSUSE 10 Security Update : ruby (ruby-6339)
High Nessus Plugin ID 42032
SynopsisThe remote openSUSE host is missing a security update.
DescriptionThis 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.
SolutionUpdate the affected ruby packages.
