Description Josh Bressers 2005-02-11 11:02:40 EST
PHP 4.0 with cURL functions allows remote attackers to bypass the open_basedir
setting and read arbitrary files via a file: URL argument to the curl_init function.

You can verify this issue with this simple php example.

$ch = curl_init("file:///etc/parla");
echo $file

Comment 4 Joe Orton 2005-03-02 11:07:54 EST
Safe mode bypasses are not considered to have "security" severity,
since the PHP interpreter does not really provide a sandbox in which
scripts are executed.
