   [security] Go 1.21.1 and Go 1.20.8 are released
   
   Hello gophers,
   
   We have just released Go versions 1.21.1 and 1.20.8, minor point releases.
   
   These minor releases include 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.
   
     Thanks to Marten Seemann for reporting this issue.
   
     This is CVE-2023-39321 and CVE-2023-39322 and Go issue https://go.dev/issue/62266.
