crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

openssl: OpenSSL TLS 1.3 server may choose unexpected key agreement group

A key group selection preference flaw has been discovered in OpenSSL. An OpenSSL TLS 1.3 server may fail to negotiate the expected preferred key exchange group when its key exchange group configuration includes the default by using the "DEFAULT" keyword. A less preferred key exchange may be used...

openssl: OpenSSL: Arbitrary code execution or denial of service through crafted PKCS#12 file

A flaw was found in OpenSSL. When an application processes a maliciously crafted PKCS12 file, an attacker can exploit a stack buffer overflow or a NULL pointer dereference. This can lead to a denial of service DoS by crashing the application, and in some cases, may enable arbitrary code execution...
