go1.15.5 (released 2020-11-12) includes security fixes to the cmd/go and math/big packages.

- go#41463 compress/flate: deflatefast produces corrupted output

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
