The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:1148 advisory.
rubygems: Delete directory using symlink when decompressing tar (CVE-2019-8320)
rubygems: Escape sequence injection vulnerability in verbose (CVE-2019-8321)
rubygems: Escape sequence injection vulnerability in gem owner (CVE-2019-8322)
rubygems: Escape sequence injection vulnerability in API response handling (CVE-2019-8323)
rubygems: Installing a malicious gem may lead to arbitrary code execution (CVE-2019-8324)
rubygems: Escape sequence injection vulnerability in errors (CVE-2019-8325)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
