Description Florian Weimer 2015-08-25 10:50:59 UTC 
It was discovered that criu service daemon allowed local users to dump
processes as long as the user and group IDs match, disregarding other
restrictions on process dumping or ptrace access.  This failure to enforce
a configured security policy may lead to information disclosure.
