Vulnerability Assessment Details

[GLSA-200410-04] PHP: Memory disclosure and arbitrary location file upload

Vulnerability Assessment Summary
PHP: Memory disclosure and arbitrary location file upload

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200410-04
(PHP: Memory disclosure and arbitrary location file upload)


Stefano Di Paola discovered two bugs in PHP. The first is a parse error in
php_variables.c that could permit a remote attacker to view the contents of
the target machine's memory. Additionally, an array processing error in the
SAPI_POST_HANDLER_FUNC() function inside rfc1867.c could lead to the
$_FILES array being overwritten.

Impact

A remote attacker could exploit the first vulnerability to view memory
contents. On a server with a script that provides file uploads, a possible hacker
could exploit the second vulnerability to upload files to an arbitrary
location. On systems where the HTTP server is permited to write in a
HTTP-accessible location, this could lead to remote execution of arbitrary
commands with the rights of the HTTP server.

Workaround

There is no known workaround at this time.
