Tracker summary

CVE-2015-8960 severity moderate: SUSE including 12 source package names (libopenssl-devel, libopenssl0_9_8, …), 50 product×package rows across 12 product lines (SUSE Linux Enterprise Desktop 11 SP3, SUSE Linux Enterprise Desktop 11 SP4, … (12 product lines)): Known Not Affected 50.

Description:

The TLS protocol 1.2 and earlier supports the rsa_fixed_dh, dss_fixed_dh, rsa_fixed_ecdh, and ecdsa_fixed_ecdh values for ClientCertificateType but does not directly document the ability to compute the master secret in certain situations with a client secret key and server public key but not a server secret key, which makes it easier for man-in-the-middle attackers to spoof TLS servers by leveraging knowledge of the secret key for an arbitrary installed client X.509 certificate, aka the "Key Compromise Impersonation (KCI)" issue.
