| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2009-09-02 | CVE-2009-3046 | Improper Certificate Validation vulnerability in Opera Browser Opera before 10.00 does not check all intermediate X.509 certificates for revocation, which makes it easier for remote SSL servers to bypass validation of the certificate chain via a revoked certificate. | 7.5 |
| 2009-07-30 | CVE-2009-2408 | Improper Certificate Validation vulnerability in multiple products Mozilla Network Security Services (NSS) before 3.12.3, Firefox before 3.0.13, Thunderbird before 2.0.0.23, and SeaMonkey before 1.1.18 do not properly handle a '\0' character in a domain name in the subject's Common Name (CN) 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. | 5.9 |
| 2008-11-13 | CVE-2008-4989 | Improper Certificate Validation vulnerability in multiple products The _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguished Name (DN). | 5.9 |
