CVE-2013-4164 – ruby: heap overflow in floating point parsing

https://notcve.org/view.php?id=CVE-2013-4164

Heap-based buffer overflow in Ruby 1.8, 1.9 before 1.9.3-p484, 2.0 before 2.0.0-p353, 2.1 before 2.1.0 preview2, and trunk before revision 43780 allows context-dependent attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a string that is converted to a floating point value, as demonstrated using (1) the to_f method or (2) JSON.parse.

CVE-2013-4073 – ruby: hostname check bypassing vulnerability in SSL client

https://notcve.org/view.php?id=CVE-2013-4073

The OpenSSL::SSL.verify_certificate_identity function in lib/openssl/ssl.rb in Ruby 1.8 before 1.8.7-p374, 1.9 before 1.9.3-p448, and 2.0 before 2.0.0-p247 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. La función OpenSSL::SSL.verify_certificate_identity en lib/openssl/ssl.rb en Ruby v1.8 anterior a v1.8.7-p374, v1.9 anterior a v1.9.3-p448, y v2.0 anterior a v2.0.0-p247 no manejar adecuadamente un carácter “\0” en un nombre de dominio en el campo Subject Alternative Name de un certificado X.509, lo que permite a atacantes "man-in-the-middle" suplantar servidores SSL de su elección mediante un certificado manipulado expedido por una Autoridad Certificadora legítima, un problema relacionado con CVE-2009-2408. • http://forums.interworx.com/threads/8000-InterWorx-Version-5-0-14-Released-on-Beta-Channel%21 http://lists.apple.com/archives/security-announce/2013/Oct/msg00004.html http://lists.opensuse.org/opensuse-updates/2013-07/msg00042.html http://lists.opensuse.org/opensuse-updates/2013-07/msg00044.html http://rhn.redhat.com/errata/RHSA-2013-1090.html http://rhn.redhat.com/errata/RHSA-2013-1103.html http://rhn.redhat.com/errata/RHSA-2013-1137.html http://support.apple.com/kb/HT6150 • CWE-310: Cryptographic Issues •
