Alpine: multiple containerd packages: security update to 1.6.12-r0
medium Tenable Cloud Security Plugin ID 403900
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- containerd is an open source container runtime. A bug was found in containerd's CRI implementation where a
user can exhaust memory on the host. In the CRI stream server, a goroutine is launched to handle terminal
resize events if a TTY is requested. If the user's process fails to launch due to, for example, a faulty
command, the goroutine will be stuck waiting to send without a receiver, resulting in a memory leak.
Kubernetes and crictl can both be configured to use containerd's CRI implementation and the stream server
is used for handling container IO. This bug has been fixed in containerd 1.6.12 and 1.5.16. Users should
update to these versions to resolve the issue. Users unable to upgrade should ensure that only trusted
images and commands are used and that only trusted users have permissions to execute commands in running
containers. (CVE-2022-23471)
