      "value": "A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981."

Los tiempos de respuesta a textos cifrados con formato incorrecto en RSA-PSK ClientKeyExchange difieren de los tiempos de respuesta de textos cifrados con el relleno PKCS#1 v1.5 correcto. Este problema puede permitir que un atacante remoto realice un ataque de canal lateral de sincronizaci\u00f3n en el intercambio de claves RSA-PSK, lo que podr\u00eda provocar la fuga de datos confidenciales. CVE-2024-0553 est\u00e1 designado como una resoluci\u00f3n incompleta para CVE-2023-5981."
