Race condition in the pkexec utility and polkitd daemon in PolicyKit (aka polkit) 0.96 allows local users to gain privileges by executing a setuid program from pkexec, related to the use of the effective user ID instead of the real user ID.

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

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.

The remote Oracle Linux 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2011-0455 advisory.

    - Include fixes for CVE-2011-1485

Tenable has extracted the preceding description block directly from the Oracle 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 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 system must be rebooted for this update to take effect.

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.

Neel Mehta discovered that a race condition in Policykit, a framework for managing administrative policies and privileges, allowed local users to elevate privileges by executing a setuid program from pkexec.

The oldstable distribution (lenny) does not contain the policykit-1 package.

Neel Mehta discovered that PolicyKit did not correctly verify the user making authorization requests. A local attacker could exploit this to trick pkexec into running applications with root privileges.

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

New polkit packages are available for Slackware 13.1 and -current to fix a security issue.

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.

- 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.

Updated polkit packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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.
