The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2020:4605 advisory.
The resource-agents packages provide the Pacemaker and RGManager service managers with a set of scripts.
These scripts interface with several services to allow operating in a high-availability (HA) environment.
Security Fix(es):
* python-httplib2: CRLF injection via an attacker controlled unescaped part of uri for httplib2.Http.request function (CVE-2020-11078)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Additional Changes:
For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.3 Release Notes linked from the References section.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
