critical Nessus Plugin ID 170001

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5800-1 advisory.

 It was discovered that Heimdal incorrectly handled certain SPNEGO tokens. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2021-44758)

 Evgeny Legerov discovered that Heimdal incorrectly handled memory when performing certain DES decryption operations. A remote attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2022-3437)

 Greg Hudson discovered that Kerberos PAC implementation used in Heimdal incorrectly handled certain parsing operations. A remote attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2022-42898)

 It was discovered that Heimdal's KDC did not properly handle certain error conditions. A remote attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2022-44640)

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.

Solution
