DEBIAN-CVE-2020-11501

GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 2018-07-16 because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks...

wildfly: The 'enabled-protocols' value in legacy security is not respected if OpenSSL security provider is in use

A flaw was found when an OpenSSL security provider is used with Wildfly, the 'enabled-protocols' value in the Wildfly configuration isn't honored. An attacker could target the traffic sent from Wildfly and downgrade the connection to a weaker version of TLS, potentially breaking the encryption...

mina-core: Retaining an open socket in close_notify SSL-TLS leading to Information disclosure.

A cryptographic protocol integrity flaw was discovered in Apache Mina. The closure of a TLS session would not always result in closure of the socket, allowing the conversation to continue in clear text. This could undermine the confidentiality of a connection and potentially disclose sensitive...

envoy: Incorrect Access Control when using SDS with Combined Validation Context

An access control bypass vulnerability was found in envoy. When the same TLS secret is used across multiple resources, the client's data, such as the subject alternative name or hash, is not validated. This flaw could lead to a possible bypass of security restrictions...

CVE-2020-8660

CNCF Envoy through 1.13.0 TLS inspector bypass. TLS inspector could have been bypassed not recognized as a TLS client by a client using only TLS 1.3. Because TLS extensions SNI, ALPN were not inspected, those connections might have been matched to a wrong filter chain, possibly bypassing some...
