Unofficial SQL-Ledger patch for CVE-2007-0667



This patch was made against SQL-Ledger 2.6.18 but just modifies a few lines in the redirect() function in the Form.pm. I have decided that it is probably best to release the patch and then wait a while before releasing full disclosure. The author of SQL-Ledger has declined to use this patch.

Best Wishes,
Chris Travers
