USN-809-1: GnuTLS vulnerabilities

Moxie Marlinspike and Dan Kaminsky independently discovered that GnuTLS did not properly handle certificates with NULL characters in the certificate name. An attacker could exploit this to perform a machine-in-the-middle attack to view sensitive information or alter encrypted communications...

CVE-2009-2730

libgnutls in GnuTLS before 2.8.2 does not properly handle a '\0' character in a domain name in the subject's 1 Common Name CN or 2 Subject Alternative Name SAN field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued b...

GnuTLS -- improper SSL certificate verification

GnuTLS reports: By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS into 1 not printing the entire CN/SAN field value when printing a certificate and 2 cause incorrect positive matches when matching a hostname against a certificate...

CVE-2009-2409

CVE-2009-2409 involves MD2 use in X.509 certificate signatures across NSS, GnuTLS, and OpenSSL. Root cause: MD2 hash weaknesses allow forging/collision-based certificate spoofing; public updates disable/avoid MD2 and patch implementations. Affected components include NSS library (Firefox usage), ...

openSUSE Security Update : gnutls (gnutls-358)

gnutls did not properly verify x509 certificate chains. An attacker could exploit that to trick client programs into trusting servers that would normally get rejected CVE-2008-4989. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were...

openSUSE Security Update : gnutls (gnutls-605)

The previous security fix for gnutls CVE-2008-4989 introduced a regression in the X.509 validation code for self-signed certificates. This update fixes this problem. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted from...
