Panic in name constraint checking for malformed certificates in crypto/x509

5.9 MediumFix available

Certificate verification can panic when a certificate in the chain has an empty DNS name and another certificate in the chain has excluded name constraints. This can crash programs that are either directly verifying X.509 certificate chains, or those that use TLS.

go1.26.0 (released 2026-02-10) is a major release of Go. go1.26.x minor releases will be provided through February 2027. https://github.com/golang/go/wiki/Go-Release-Cycle go1.26 arrives six months after Go 1.25. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. (boo#1255111)

  • Language change: The built-in new function, which creates a new variable, now allows its operand to be an expression, specifying the initial value of the variable.
  • Language change: The restriction that a generic type may not refer to itself in its type parameter list has been lifted. It is now possible to specify type constraints that refer to the generic type being constrained.
  • go command: The venerable go fix…
