Fedora 20 : polkit-0.112-1.fc20 (2013-17160)

high Nessus Plugin ID 70063

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

This release fixes CVE-2013-4288: Race condition with process subjects that do not have securely determined uid.

pkcheck(1) now supports a new format for the --process argument; all applications need to use the new format to avoid a race condition (or use --system-bus-name to identify the process instead).

Similarly, applications using the API should always use polkit_unix_process_new_for_owner(). polkit_unix_process_new() and polkit_unix_process_new_full() are unsafe and have been deprecated.

Thanks to Sebastian Krahmer of the SUSE Security Team for reporting this issue.

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.

Solution

Update the affected polkit package.
