openssl: openssl: Traffic amplification Denial of Service via QUIC packet over-accounting

A flaw was found in OpenSSL. This vulnerability allows a remote attacker to abuse the server to amplify network traffic in a Denial of Service DoS attack. When the server is configured without client address validation, incoming datagrams containing multiple QUIC packets cause the server to...

openssl: openssl: Denial of Service via excessive memory allocation in CRL distribution point processing

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS by presenting a specially crafted certificate during a Transport Layer Security TLS handshake. When OpenSSL processes and caches certificate extensions containing numerous Certificate Revocation List CRL distribution...

openssl: openssl: Denial of Service via excessive QUIC packet buffer retention

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS by sending specially crafted network packets to a QUIC protocol endpoint. Because the QUIC stack retains memory in packet buffers until the receiving application reads the stream data, an attacker can manipulate data...

openssl: OpenSSL: Denial of Service via unbounded QUIC connection identifier backlog

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS by flooding a connection with connection identifier update requests while withholding acknowledgments. This behavior bypasses connection limits and forces the system to accumulate pending retirement frames, resulting...

openssl: openssl: information disclosure via non-constant-time SM2 scalar multiplication on ARM64 and RISC-V

A flaw was found in OpenSSL. The optimized scalar point multiplication used for SM2 cryptographic operations on ARM64 and RISC-V architectures does not execute in constant time. An attacker capable of measuring execution times or observing processor cache-access patterns can exploit this side...

openssl: openssl: Denial of Service via crafted CMP certificate revocation response

A flaw was found in OpenSSL. When a Certificate Management Protocol CMP client requests certificate revocation using a PKCS10 Certificate Signing Request CSR, it omits the certificate issuer name and serial number. A malicious or compromised CMP server, or an attacker possessing valid message...

openssl: OpenSSL: Denial of Service via undersized DTLS record

A flaw was found in OpenSSL. A remote, unauthenticated attacker can cause a Denial of Service DoS by terminating an active Datagram Transport Layer Security DTLS session. By sending an undersized network packet that is shorter than the expected cryptographic overhead, the record processing layer...

openssl: OpenSSL: Private key recovery via SM2 timing side-channel

A flaw was found in OpenSSL. During SM2 signature generation, variable-time arithmetic operations are performed on secret values, creating an observable timing side-channel. An attacker capable of measuring signature generation times can collect timing data across multiple signing operations, whi...

openssl: OpenSSL: Denial of Service via unenforced QUIC connection flow control

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS due to missing connection-level flow control enforcement in the QUIC protocol implementation. By opening multiple streams that respect individual stream limits while preventing data consumption, the attacker can forc...

openssl: openssl: Denial of Service via out-of-bounds write during TLS context switch

A flaw was found in openssl. When a server replaces its security context during an active Transport Layer Security TLS handshake, it fails to update the internal capacity tracking for cryptographic signature algorithms. A remote peer can exploit this issue by advertising specific signature...
