LAYER: meta-oe PACKAGE NAME: polkit PACKAGE VERSION: 124 CVE: CVE-2013-4288 CVE STATUS: Patched CVE SUMMARY: Race condition in PolicyKit (aka polkit) allows local users to bypass intended PolicyKit restrictions and gain privileges by starting a setuid or pkexec process before the authorization check is performed, related to (1) the polkit_unix_process_new API function, (2) the dbus API, or (3) the --process (unix-process) option for authorization to pkcheck.

The implementation of the polkit_backend_interactive_authority_check_authorization function in polkitd allows to test for authentication and trigger authentication of unrelated processes owned by other users. This may result in a local DoS and information disclosure.

This is related to lack of uid checking in polkitbackend/polkitbackendinteractiveauthority.c.

This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine.

The highest threat from this vulnerability is to availability.
