| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2012-11-04 | CVE-2012-3446 | Improper Certificate Validation vulnerability in Apache Libcloud Apache Libcloud before 0.11.1 uses an incorrect regular expression during verification of whether the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a crafted certificate. | 5.9 |
| 2012-09-18 | CVE-2012-2993 | Improper Certificate Validation vulnerability in Microsoft Windows Phone 7 Firmware Microsoft Windows Phone 7 does not verify the domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof an SSL server for the (1) POP3, (2) IMAP, or (3) SMTP protocol via an arbitrary valid certificate. | 5.9 |
| 2011-06-24 | CVE-2011-0199 | Improper Certificate Validation vulnerability in Apple mac OS X and mac OS X Server The Certificate Trust Policy component in Apple Mac OS X before 10.6.8 does not perform CRL checking for Extended Validation (EV) certificates that lack OCSP URLs, which might allow man-in-the-middle attackers to spoof an SSL server via a revoked certificate. | 5.9 |
| 2010-11-15 | CVE-2010-1378 | Improper Certificate Validation vulnerability in Apple mac OS X and mac OS X Server OpenSSL in Apple Mac OS X 10.6.x before 10.6.5 does not properly perform arithmetic, which allows remote attackers to bypass X.509 certificate authentication via an arbitrary certificate issued by a legitimate Certification Authority. | 9.8 |
| 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 |
