Log Message:
go120: update to 1.20.8 (security)

This minor releases includes 4 security fixes following the security policy:

- cmd/go: go.mod toolchain directive allows arbitrary execution

  The go.mod toolchain directive, introduced in Go 1.21, could be leveraged to
  execute scripts and binaries relative to the root of the module when the
  "go" command was executed within the module. This applies to modules
  downloaded using the "go" command from the module proxy, as well as \ 
modules
  downloaded directly using VCS software.

  Thanks to Juho Nurminen of Mattermost for reporting this issue.

  This is CVE-2023-39320 and Go issue https://go.dev/issue/62198.

- html/template: improper handling of HTML-like comments within script
  contexts

  The html/template package did not properly handle HMTL-like \ 
"<!--" and "-->"
  comment tokens, nor hashbang "#!" comment tokens, in <script> \ 
contexts. This
  may cause the template parser to improperly interpret the contents of
  <script> contexts, causing actions to be improperly escaped. This could be
  leveraged to perform an XSS attack.

  Thanks to Takeshi Kaneko (GMO Cybersecurity by Ierae, Inc.) for reporting
  this issue.

  This is CVE-2023-39318 and Go issue https://go.dev/issue/62196.

- html/template: improper handling of special tags within script contexts

  The html/template package did not apply the proper rules for handling
  occurrences of "<script", "<!--", and \ 
"</script" within JS literals in
  <script> contexts.  This may cause the template parser to improperly
  consider script contexts to be terminated early, causing actions to be
  improperly escaped. This could be leveraged to perform an XSS attack.

  Thanks to Takeshi Kaneko (GMO Cybersecurity by Ierae, Inc.) for reporting
  this issue.

  This is CVE-2023-39319 and Go issue https://go.dev/issue/62197.

- crypto/tls: panic when processing post-handshake message on QUIC connections

  Processing an incomplete post-handshake message for a QUIC connection caused
  a panic.
