"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0214 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2024-0553:
    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-2024-28834:
    A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits
    deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such
    as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce size
    from 513 to 512 bits, exposing a potential timing side-channel.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
