cmd/go: line directives allows arbitrary execution during build

"//line" directives can be used to bypass the restrictions on \ 
"//go:cgo_"
directives, allowing blocked linker and compiler flags to be passed during
compliation. This can result in unexpected execution of arbitrary code when
running "go build". The line directive requires the absolute path of \ 
the file in
which the directive lives, which makes exploting this issue significantly more
complex.

This is CVE-2023-39323 and Go issue https://go.dev/issue/63211.

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.

  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.

  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.

Log message:
go120: update to 1.20.7 (security)

go1.20.7 (released 2023-08-01) includes a security fix to the crypto/tls
package, as well as bug fixes to the assembler and the compiler. See the Go
1.20.7 milestone on our issue tracker for details.

Log message:
Update go119 to 1.19.12 (security).

crypto/tls: restrict RSA keys in certificates to <= 8192 bits

Extremely large RSA keys in certificate chains can cause a client/server
to expend significant CPU time verifying signatures. Limit this by
restricting the size of RSA keys transmitted during handshakes to <=
8192 bits.

Based on a survey of publicly trusted RSA keys, there are currently only
three certificates in circulation with keys larger than this, and all
three appear to be test certificates that are not actively deployed. It
is possible there are larger keys in use in private PKIs, but we target
the web PKI, so causing breakage here in the interests of increasing the
default safety of users of crypto/tls seems reasonable.

Thanks to Mateusz Poliwczak for reporting this issue.

net/http: insufficient sanitization of Host header

The HTTP/1 client did not fully validate the contents of the Host header. A
maliciously crafted Host header could inject additional headers or entire
requests. The HTTP/1 client now refuses to send requests containing an invalid
Request.Host or Request.URL.Host value.

Log message:
go120: update to 1.20.5 (security)

This minor release includes 3 security fixes following the security policy:

- cmd/go: cgo code injection

  The go command may generate unexpected code at build time when using cgo. This
  may result in unexpected behavior when running a go program which uses cgo.

  This may occur when running an untrusted module which contains directories
  with newline characters in their names. Modules which are retrieved using the
  go command, i.e. via "go get", are not affected (modules retrieved using
  GOPATH-mode, i.e.  GO111MODULE=off, may be affected).

  Thanks to Juho Nurminen of Mattermost for reporting this issue.

  This is CVE-2023-29402 and Go issue https://go.dev/issue/60167.

- runtime: unexpected behavior of setuid/setgid binaries

  The Go runtime didn't act any differently when a binary had the setuid/setgid
  bit set. On Unix platforms, if a setuid/setgid binary was executed with
  standard I/O file descriptors closed, opening any files could result in
  unexpected content being read/written with elevated prilieges. Similarly if a
  setuid/setgid program was terminated, either via panic or signal, it could
  leak the contents of its registers.

  Thanks to Vincent Dehors from Synacktiv for reporting this issue.

  This is CVE-2023-29403 and Go issue https://go.dev/issue/60272.

- cmd/go: improper sanitization of LDFLAGS

  The go command may execute arbitrary code at build time when using cgo. This
  may occur when running "go get" on a malicious module, or when \ 
running any
  other command which builds untrusted code. This is can by triggered by linker
  flags, specified via a "#cgo LDFLAGS" directive.

  Thanks to Juho Nurminen of Mattermost for reporting this issue.
