CVE-2014-8989

Priority
Description
The Linux kernel through 3.17.4 does not properly restrict dropping of
supplemental group memberships in certain namespace scenarios, which 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, aka a "negative groups" issue, related to
kernel/groups.c, kernel/uid16.c, and kernel/user_namespace.c.
Ubuntu-Description
A flaw was discovered in how supplemental group memberships are handled in
certain namespace scenarios. A local user could exploit this flaw to bypass
file permission restrictions.
Notes
jdstrandandroid kernels (flo, goldfish, grouper, maguro, mako and manta) are
not supported on the Ubuntu Touch 14.04 preview kernels
linux-lts-saucy no longer receives official support
linux-lts-quantal no longer receives official support
sbeattiefor precise/3.2 kernel, prio is low, due to lack of support
for unprivileged user namespaces
