openssl: OpenSSL: Arbitrary code execution due to use-after-free in DANE TLSA authentication

A flaw was found in OpenSSL. An uncommon configuration of clients performing DANE TLSA-based server authentication, when paired with uncommon server DANE TLSA records, may result in a use-after-free and/or double-free on the client side. This vulnerability could lead to data corruption, applicati...

CVE-2026-34582

A flaw was found in Botan, a C++ cryptography library. The TLS 1.3 implementation in Botan allows application data to be processed before the TLS handshake is fully completed. A remote attacker can exploit this by omitting critical client authentication messages, such as the Certificate,...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in the DANE client authentication process. An attacker can cause memory corruption, application crashes, or potentially execute arbitrary code by manipulating TLSA records with both PKIX-TA/PKIX-EE and DANE-TA certificate...
