CVE-2016-4998 (retired)

Priority
Description
The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem
in the Linux kernel before 4.6 allows local users to cause a denial of
service (out-of-bounds read) or possibly obtain sensitive information from
kernel heap memory by leveraging in-container root access to provide a
crafted offset value that leads to crossing a ruleset blob boundary.
Ubuntu-Description
Jesse Hertz and Tim Newsham discovered that the Linux netfilter
implementation did not correctly perform validation when handling
IPT_SO_SET_REPLACE events. A local unprivileged attacker could use this to
cause a denial of service (system crash) or obtain potentially sensitive
information from kernel memory.
Notes
 jdstrand> android kernels (flo, goldfish, grouper, maguro, mako and manta) are
  not supported on the Ubuntu Touch 14.10 and earlier preview kernels
 jdstrand> linux-lts-saucy no longer receives official support
 jdstrand> linux-lts-quantal no longer receives official support
 sarnold> Can be mitigated against by a sysctl to disable userns support
