An update of the gnutls package has been released.

According to the versions of the gnutls packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - 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. (CVE-2024-0553)

  - A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with     distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure.
    This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack.
    (CVE-2024-0567)

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6593-1 advisory.

    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.
    (CVE-2024-0553)

    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. (CVE-2024-0567)
