OpenSSL

Issue summary: An established DTLS 1.2 association using an AEAD cipher suite can be terminated by a single unauthenticated datagram whose encrypted fragment is shorter than the mandatory explicit IV…

Corregida en Debian 13, Ubuntu 22.04, Ubuntu 24.04 y Ubuntu 26.04.

OpenSSL

Issue summary: SM2 signature generation uses non-constant-time arithmetic on secret values, forming a timing side-channel. Impact summary: An attacker able to measure SM2 signing times may learn…

Corregida en Ubuntu 22.04, Ubuntu 24.04 y Ubuntu 26.04.

OpenSSL

Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than the record itself requires. Impact summary: A peer can use a…

Corregida en Debian 13 y Debian 14.

OpenSSL

Issue summary: OpenSSL CMS decryption sizes the key-unwrap output buffer based on querying the unwrapped key size, but the AES-WRAP-PAD unwrap primitive can write and cleanse more bytes than that…

Corregida en Debian 13 y Debian 14.

OpenSSL

Issue summary: The OpenSSL Certificate Management Protocol (CMP) caches additional certificates (extraCerts) sent in a CMP message, but never expunges them (for instance if they are invalid). If a…

Corregida en Debian 13 y Debian 14.

OpenSSL

Issue summary: OpenSSL CMP password based protection verification only checks whether the protectionAlg parameter was not NULL and not its ASN.1 type, before treating it as a PBMParameter. A crafted…

Corregida en Debian 13 y Debian 14.

OpenSSL

Issue summary: ChaCha20-Poly1305 and AES-OCB decryption with an empty ciphertext can report success without verifying the supplied authentication tag when the operation is finalized by calling the…

Corregida en Debian 13 y Debian 14.

OpenSSL

Issue summary: A malicious TLS server can cause a memory leak in a TLS client that has enabled OCSP response checking by sending an OCSP response that contains no single response entries. Impact…
