CVE-2009-2409

Status Candidate

Overview

The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large.

Mandriva Linux Security Advisory 2009-197 - Security issues in nss prior to 3.12.3 could lead to a man-in-the-middle attack via a spoofed X.509 certificate and md2 algorithm flaws, and also cause a denial-of-service and possible code execution via a long domain name in X.509 certificate. This update provides the latest versions of NSS and NSPR libraries which are not vulnerable to those attacks. Packages for 2008.0 are being provided due to extended support for Corporate products.

Debian Linux Security Advisory 1935-1
Posted Nov 18, 2009
Authored by Debian | Site debian.org

Debian Linux Security Advisory 1935-1 - Dan Kaminsky and Moxie Marlinspike discovered that gnutls, an implementation of the TLS/SSL protocol, does not properly handle a '\\0' character in a domain name in the subject's Common Name or 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 by a legitimate Certification Authority. In addition, with this update, certificates with MD2 hash signatures are no longer accepted since they're no longer considered cryptograhically secure.

Mandriva Linux Security Advisory 2009-239 - Use-after-free vulnerability in the dtls1_retrieve_buffered_fragment function in ssl/d1_both.c in OpenSSL 1.0.0 Beta 2 allows remote attackers to cause a denial of service (openssl s_client crash) and possibly have unspecified other impact via a DTLS packet, as demonstrated by a packet from a server that uses a crafted server certificate. The dtls1_retrieve_buffered_fragment function in ssl/d1_both.c in OpenSSL before 1.0.0 Beta 2 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence DTLS handshake message, related to a fragment bug. The NSS library library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws the scope of this issue is currently limited because the amount of computation required is still large. This update provides a solution to these vulnerabilities.

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice USN-810-1 - Moxie Marlinspike discovered that NSS did not properly handle regular expressions in certificate names. A remote attacker could create a specially crafted certificate to cause a denial of service (via application crash) or execute arbitrary code as the user invoking the program. Moxie Marlinspike and Dan Kaminsky independently discovered that NSS did not properly handle certificates with NULL characters in the certificate name. An attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. Dan Kaminsky discovered NSS would still accept certificates with MD2 hash signatures. As a result, an attacker could potentially create a malicious trusted certificate to impersonate another site.
