| Vetor | AV:L/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 3.17.5
Description
The issue allows local users to bypass intended file permissions by leveraging a POSIX ACL containing an entry for the group category that is more restrictive than the entry for the other category. This is related to certain namespace scenarios where the Linux kernel does not properly restrict dropping of supplemental group memberships.
Recommendations
For Linux kernel versions prior to 3.17.5, update to version 3.17.5 or later to resolve the issue.
