Teler · Teler · CVE-2020-26213
**Name of the Vulnerable Software and Affected Versions**
teler versions prior to 0.0.1
**Description**
The issue causes a denial-of-service (`SIGSEGV`) when teler is run inside a Docker container and encounters the `errors.Exit` function. This is because it doesn't get the process ID and process group ID of teler properly to kill.
**Recommendations**
For versions prior to 0.0.1, upgrade to version 0.0.1 or later to resolve the issue. As a temporary workaround, consider avoiding the use of the `errors.Exit` function when running teler inside a Docker container until a patch is applied.
