in thread Taint, CGI and perl 5.10

I will try to cut the code down to the smallest instance where the problem still occurs and repost in a bit. Essentially the problem is this:

  • using perl 5.8
  • code working with taint mode turned on, file name comes from user, untainted by code and tainted information written to file successfully.
  • upgrade to 5.10
  • code now broken with 'insecure dependency...' error
  • only way to fix is to untaint the information written to the file. Nothing else changed.
I pass a file handle and the tainted information to a subroutine that does the output. I don't know if that makes a difference. Back in a bit with code sample.

    The above does exactly what you said except it gives no error with 5.10.0.
