Amazon Linux AMI : containerd (ALAS-2020-1455)

medium Nessus Plugin ID 143367

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1455 advisory.

 - Access controls for the shim's API socket verified that the connecting process had an effective UID of 0, but did not otherwise restrict access to the abstract Unix domain socket. This would allow malicious containers running in the same network namespace as the shim, with an effective UID of 0 but otherwise reduced privileges, to cause new processes to be run with elevated privileges. (CVE-2020-15257)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
