The go 1.18.9 version fixes a vulnerability GO-2022-1144, which concerns
the net/http and golang.org/x/net packages.
These are used in the codebase, and therefore automated tools report the
generated binaries as vulnerable to this.
Note that while Packer is indeed vulnerable to this, this is a DoS
attack. This is therefore unlikely to impact Packer severely, especially
as it requires a deliberate attempt to provoke an OOM/excessive GC
cycles.
Nonetheless, since this vulnerability is fixed with go 1.18.9, we bump
the version used to build/test the tools to this version.
This change updates Packer core Go version to 1.18. The move to Go 1.18 and not Go 1.19
is to allow the HCP Packer SDK time to upgrade to Go 1.18.
Changes Made:
* Bump go mod file to use Go 1.18
* Bump release pipeline to use Go 1.18
* Update plugin updater script to run go mod tidy for Go 1.18
* Update Linux job to use setup-go action
