Describe CVE-2004-1020.
What is CVE-2004-1020?
The addslashes function in PHP 4.3.9 does not properly escape a NULL (/0) character, which may allow remote attackers to read arbitrary files in PHP applications that contain a directory traversal vulnerability in require or include statements, but are otherwise protected by the magic_quotes_gpc mechanism.  NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute.  This candidate may change significantly in the future as a result of further discussion..
