Perl variables (scalars, hashes, arrays) expand dynamically as needed to accomodate data. So unless there is a bug in the core perl implementation of those types (or you have them tied to something that imposes such a limitation) you're effecitvely safe from something in perl causing a buffer overflow to execute remote code. This isn't saying that youre safe from a large piece of data causing a perl processes to use too much memory and crash the server (DOS style attack), or that something before or after perl (the web server or DB server) might not exhibit such a buffer overflow vulnerability that could be expolited through your code (even though your code itself may not be vulnerable).

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.
