"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2022:0117 advisory.

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

    CVE-2019-10195:
    A flaw was found in IPA, all 4.6.x versions before 4.6.7, all 4.7.x versions before 4.7.4 and all 4.8.x
    versions before 4.8.3, in the way that FreeIPA's batch processing API logged operations. This included
    passing user passwords in clear text on FreeIPA masters. Batch processing of commands with passwords as
    arguments or options is not performed by default in FreeIPA but is possible by third-party components. An
    attacker having access to system logs on FreeIPA masters could use this flaw to produce log file content
    with passwords exposed.

    CVE-2019-14867:
    A flaw was found in IPA, all 4.6.x versions before 4.6.7, all 4.7.x versions before 4.7.4 and all 4.8.x
    versions before 4.8.3, in the way the internal function ber_scanf() was used in some components of the IPA
    server, which parsed kerberos key data. An unauthenticated attacker who could trigger parsing of the krb
    principal key could cause the IPA server to crash or in some conditions, cause arbitrary code to be
    executed on the server hosting the IPA server.

    CVE-2020-25719:
    A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-
    based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did
    not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total
    domain compromise.

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.");
