Description Carlos López 2022-06-07 13:18:49 UTC
rh#2085361

A vulnerability was found in CRI-O that causes memory exhaustion on the node for anyone with access to the kube api. The ExecSync request runs commands in a container and logs the output of the command. This output is then read by cri-o after command execution, and it is read in a manner where the entire file corresponding to the output of the command is read in. Thus, if the output of the command is large it is possible to exhaust the memory of the node when crio reads output of the command.
