FreeBSD 10.3 Jail SHM Issue

FreeBSD 10.3 Jail SHM Issue
Posted Aug 16, 2017
Authored by WhiteWinterWolf

FreeBSD jail incompletely protects the access to the IPC primitives. The 'allow.sysvipc' setting only affects IPC queues, leaving other IPC objects unprotected, making them reachable system-wide independently of the system configuration. Versions 7.0 through 10.3 are affected. Proof of concept included.
