Astra Linux – Vulnerability in OpenSSL

Issue summary: Clients that use RFC7250 Raw Public Keys RPKs to authenticate a server may fail to notice that the server was not authenticated, because the handshake does not abort as expected when the SSLVERIFYPEER verification mode is set. Impact summary: TLS and DTLS connections that use raw...

Envoy crashes when HTTP ext_proc processes local replies

Summary Envoy's extproc HTTP filter is at risk of crashing if a local reply is sent to the external server due to the filter's life time issue. A known situation is the fail of a websocket handshake will trigger a local reply leading to the crash of Envoy. PoC If both websocket and extproc are...

Authentication Bypass

OpenSSL is vulnerable to Authentication Bypass. The vulnerability is due to SSLVERIFYPEER not enforcing handshake failure when the server's RPK does not match an expected key, allowing unauthenticated connections to proceed...

scandium: Failing DTLS handshakes may cause throttling to block processing of records

A flaw was found in the Eclipse Californium Scandium package. This issue occurs when failing handshakes don't clean up counters for throttling, causing the threshold to be reached without being released again, resulting in a denial of service. An attacker could submit a high quantity of server...

SUSE CVE-2022-1434
