Google and Red Hat have released a patch for a critical security vulnerability in the widely used GNU C library (glibc). The leak allows an attack, whereby, through a stack-based buffer overflow, arbitrary code can be executed.

Due to the seriousness of this issue, we have decided to patch this vulnerability during a maintenance window scheduled ahead of our regular maintenance windows. During maintenance, all nodes within the Fuga platform will receive a reboot, resulting in a short downtime of instances running on it. There may also be short disruptions to connectivity while we patch and reboot networking components.
