CVE-2009-5138 – gnutls: incorrect handling of V1 intermediate certificates

https://notcve.org/view.php?id=CVE-2009-5138

GnuTLS before 2.7.6, when the GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT flag is not enabled, treats version 1 X.509 certificates as intermediate CAs, which allows remote attackers to bypass intended restrictions by leveraging a X.509 V1 certificate from a trusted CA to issue new certificates, a different vulnerability than CVE-2014-1959. GnuTLS anterior a 2.7.6, cuando el indicador GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT no está habilitado, trata certificados X.509 de versión 1 como CAs intermedios, lo que permite a atacantes remotos evadir restricciones mediante el aprovechamiento de un certificado X.509 V1 de un CA confiable para emitir certificados nuevos, una vulnerabilidad diferente a CVE-2014-1959. • http://article.gmane.org/gmane.comp.security.oss.general/12223 http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00020.html http://rhn.redhat.com/errata/RHSA-2014-0247.html http://secunia.com/advisories/57254 http://secunia.com/advisories/57260 http://sec • CWE-264: Permissions, Privileges, and Access Controls CWE-295: Improper Certificate Validation •
