USN-810-3: NSS regression

USN-810-1 fixed vulnerabilities in NSS. Jozsef Kadlecsik noticed that the new libraries on amd64 did not correctly set stack memory flags, and caused applications using NSS e.g. Firefox to have an executable stack. This reduced the effectiveness of some defensive security protections. This update...

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...

USN-818-1: curl vulnerability

Scott Cantor discovered that Curl did not correctly handle SSL certificates with zero bytes in the Common Name. A remote attacker could exploit this to perform a machine-in-the-middle attack to view sensitive information or alter encrypted communications...

USN-816-1: fetchmail vulnerability

Matthias Andree discovered that fetchmail did not properly handle certificates with NULL characters in the certificate name. A remote attacker could exploit this to perform a machine-in-the-middle attack to view sensitive information or alter encrypted communications...

USN-810-1: NSS vulnerabilities

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. CVE-2009-2404 Moxie...

USN-704-1: OpenSSL vulnerability

It was discovered that OpenSSL did not properly perform signature verification on DSA and ECDSA keys. If user or automated system connected to a malicious server or a remote attacker were able to perform a machine-in-the-middle attack, this flaw could be exploited to view sensitive information...

USN-678-1: GnuTLS vulnerability

Martin von Gagern discovered that GnuTLS did not properly verify certificate chains when the last certificate in the chain was self-signed. If a remote attacker were able to perform a machine-in-the-middle attack, this flaw could be exploited to view sensitive information. CVE-2008-4989...

USN-596-1: Ruby vulnerabilities

Chris Clark discovered that Ruby's HTTPS module did not check for commonName mismatches early enough during SSL negotiation. If a remote attacker were able to perform machine-in-the-middle attacks, this flaw could be exploited to view sensitive information in HTTPS requests coming from Ruby...

USN-483-1: libnet-dns-perl vulnerabilities

Peter Johannes Holzer discovered that the Net::DNS Perl module had predictable sequence numbers. This could allow remote attackers to carry out DNS spoofing, leading to possible machine-in-the-middle attacks. CVE-2007-3377 Steffen Ullrich discovered that the Net::DNS Perl module did not correctly...
