v1.1.12 -- "Now you're thinking with Portals™!" This is the twelfth patch release in the 1.1.z release branch of runc. It fixes a high-severity container breakout vulnerability involving leaked file descriptors, and users are strongly encouraged to update as soon as possible. * Fix CVE-2024-21626, a container breakout attack that took advantage of a file descriptor that was leaked internally within runc (but never leaked to the container process). In addition to fixing the leak, several strict hardening measures were added to ensure that future internal leaks could not be used to break out in this manner again. Based on our research, while no other container runtime had a similar leak, none had any of the hardening steps we've introduced (and some runtimes would not check for any file descriptors that a calling process may have leaked to them, allowing for container breakouts due to basic user error).
