Newest publication first
A flaw was found in CRIU's handling of restartable sequences (rseq) during checkpoint/restore. A malicious process inside a container can register an rseq critical section that hijacks CRIU's parasite code injection during checkpoint, allowing it to spoof the process credentials...
The service daemon in CRIU does not properly restrict access to non-dumpable processes, which allows local users to obtain sensitive information via (1) process dumps or (2) ptrace access.
The service daemon in CRIU creates log and dump files insecurely, which allows local users to create arbitrary files and take ownership of existing files via unspecified vectors related to a directory path.
