deprecate MD2 in SSL cert validation (Kaminsky)

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...

nss regexp heap overflow

Heap-based buffer overflow in a regular-expression parser in Mozilla Network Security Services NSS before 3.12.3, as used in Firefox, Thunderbird, SeaMonkey, Evolution, Pidgin, and AOL Instant Messenger AIM, allows remote SSL servers to cause a denial of service application crash or possibly...

firefox/nss: doesn't handle NULL in Common Name properly

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...

openSUSE Security Update : gnutls (gnutls-358)

CVE-2008-4989

The gnutlsx509verifycertificate 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 Distinguishe...

openssl signature forgery

OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8 before 0.9.8c, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS 1 v1.5 signature that is signed by that RSA key and prevents OpenSSL from correctly verifying...

openssl public key DoS

OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows attackers to cause a denial of service CPU consumption via parasitic public keys with large 1 "public exponent" or 2 "public modulus" values in X.509 certificates that require extra time to process when using RSA...

Debian OpenSSH/OpenSSL Package Random Number Generator Weakness (SSL check)

The remote x509 certificate on the remote SSL server has been generated on a Debian or Ubuntu system which contains a bug in the random number generator of its OpenSSL library. The problem is due to a Debian packager removing nearly all sources of entropy in the remote version of OpenSSL. An...
