-Subject: [PATCH] Correct handling of capabilities
-
-Ensure that capabilities are properly handled for non-root users
-in privileged containers. We do not want to give full caps, but
-instead only CapInh and CapEff (others should be all-zeroes).
-
-Fixing `podman run` is easy - the same code as the Podman 1.6 fix
-works there. The `podman exec` command is far more challenging.
-Exec received a complete rewrite to use Conmon at some point
-before Podman 1.6, and gained many capabilities in the process.
-One of those was the ability to actually tweak the capabilities
-of the exec process - 1.0 did not have that. Since it was needed
-to resolve this CVE, I was forced to backport a large bit of the
-1.0 -> 1.6 exec changes (passing a Process block to the OCI
-runtime, and using `prepareProcessExec()` to prepare said block).
-I am honestly uncomfortable with the size and scope of this
-change but I don't see another way around this.
-
-Fixes CVE-2021-20188
