CVE-2017-5123
Published: 12 October 2017
Insufficient data validation in waitid allowed an user to escape sandboxes on Linux.
From the Ubuntu Security Team
Chris Salls discovered a missing access check in the waitid() system call implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
