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...

openssl: OpenSSL: Heap buffer overflow on 32-bit systems from large X.509 certificate processing

A flaw was found in OpenSSL. This vulnerability, a heap buffer overflow, affects 32-bit systems when processing an unusually large X.509 certificate. If an application or service attempts to print or log such a specially crafted certificate, it could lead to a system crash or potentially allow an...

openssl: OpenSSL: Denial of Service due to excessive memory allocation in TLS 1.3 certificate compression

A flaw was found in OpenSSL. A remote attacker can exploit this vulnerability by sending a specially crafted CompressedCertificate message during the TLS 1.3 handshake. This can cause excessive per-connection memory allocations, leading to resource exhaustion and a Denial of Service DoS for...

crypto/tls: crypto/tls: Incorrect certificate validation during TLS session resumption

A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security TLS session resumption when certificate authority CA settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing ...
