Descriptions
A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the 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.
Se encontró una vulnerabilidad en GnuTLS. 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 sincronización en el intercambio de claves RSA-PSK, lo que podría provocar la fuga de datos confidenciales. CVE-2024-0553 está designado como una resolución incompleta para CVE-2023-5981.
It was discovered that GnuTLS had a timing side-channel when processing malformed ciphertexts in RSA-PSK ClientKeyExchange. A remote attacker could possibly use this issue to recover sensitive information. It was discovered that GnuTLS incorrectly handled certain certificate chains with a cross-signing loop. A remote attacker could possibly use this issue to cause GnuTLS to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS, Ubuntu 23.04, and Ubuntu 23.10.
