Hi! Dirty COW allows privilege-escalation via writing /proc/self/mem
PoC https://github.com/dirtycow/dirtycow.github.io/blob/master/d irtyc0w.c demonstrates writing to root owned file by unprivileged user. Does this PE vulnerability potentially allow escape from OpenVZ container?

Dear hordar,
This question requires additional investigation.
At present we do not know about escapes from container, but we cannot exclude this.

Thank you,
Vasily Averin
