( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Since Lincoln Stein has added these global variables in CGI.pm, he's clearly aware of DOS problems. He has these fairly well documented in his POD, so I also wonder why they're not set. My guess is that he realizes that there is a hole here but he's trying to maintain backwards compatibility.

I understand that one or both of these variables have been removed in CGI.pm versions 3+, so I'm curious how this situation has been addressed. tachyon raised this issue in this post about a security problem with 3.01. Since these globals don't appear to be present, it seems that this code wouldn't work for the newer versions.

Cheers,
Ovid

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
