"The CentOS Linux 7.9 host has a package installed that is affected by multiple vulnerabilities as referenced in the CIQ
ciqsa-2026_1650 advisory.

    This advisory aggregates security fixes for the unzip SRPM in CIQ CentOS Bridge 7.9. It addresses 9 CVEs:
    CVE-2019-13232, CVE-2018-1000035, CVE-2005-4667, CVE-2008-0888, CVE-2014-8139, and 4 more.

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

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