CVE-2020-26213
In teler before version 0.0.1, if you run teler inside a Docker container and encounter `errors.Exit` function, it will cause denial-of-service (`SIGSEGV`) because it doesn't get process ID and process group ID of teler properly to kills.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
