The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6937-1 advisory.

    It was discovered that OpenSSL incorrectly handled TLSv1.3 sessions when certain non-default TLS server     configurations were in use. A remote attacker could possibly use this issue to cause OpenSSL to consume     resources, leading to a denial of service. (CVE-2024-2511)

    It was discovered that OpenSSL incorrectly handled checking excessively long DSA keys or parameters. A     remote attacker could possibly use this issue to cause OpenSSL to consume resources, leading to a denial     of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-4603)

    William Ahern discovered that OpenSSL incorrectly handled certain memory operations in a rarely-used API.
    A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or     possibly execute arbitrary code. (CVE-2024-4741)

    Joseph Birr-Pixton discovered that OpenSSL incorrectly handled calling a certain API with an empty     supported client protocols buffer. A remote attacker could possibly use this issue to obtain sensitive     information, or cause OpenSSL to crash, resulting in a denial of service. (CVE-2024-5535)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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