A vulnerability has been found and corrected in polkit :

A race condition flaw was found in the PolicyKit pkexec utility and polkitd daemon. A local user could use this flaw to appear as a privileged user to pkexec, allowing them to execute arbitrary commands as root by running those commands with pkexec (CVE-2011-1485).

The updated packages have been patched to correct this issue.

The remote host is affected by the vulnerability described in GLSA-201204-06 (PolicyKit: Multiple vulnerabilities)

    Multiple vulnerabilities have been found in PolicyKit:
      Error messages in the pkexec utility disclose the existence of local         files (CVE-2010-0750).
      The pkexec utility initially checks the effective user ID of its         parent process for authorization, instead of checking the real user ID         (CVE-2011-1485).
      Members of the 'wheel' group are able to execute commands as an         administrator without a password (CVE-2011-4945).
  Impact :

    A local attacker could gain elevated privileges or sensitive       information.
  Workaround :

    There is no known workaround at this time.

The remote OracleVM system is missing necessary patches to address critical security updates :

  - Fix of CVE-2019-6133, PID reuse via slow fork

  - Resolves: rhbz#1667310

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:0455 advisory.

    PolicyKit is a toolkit for defining and handling authorizations.

    A race condition flaw was found in the PolicyKit pkexec utility and polkitd     daemon. A local user could use this flaw to appear as a privileged user to     pkexec, allowing them to execute arbitrary commands as root by running     those commands with pkexec. (CVE-2011-1485)

    Red Hat would like to thank Neel Mehta of Google for reporting this issue.

    All polkit users should upgrade to these updated packages, which contain     backported patches to correct this issue. The system must be rebooted for     this update to take effect.

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.

A race condition exists in pkexec while trying to determine its caller which could lead to privilege escalation. CVE-2011-1485 has been assigned to this issue.

- Bug #692922 - CVE-2011-1485 polkitd/pkexec vulnerability

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
