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

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

Detailed Explanation for this Vulnerability Test
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 allow 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.


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 allowed to write in a
HTTP-accessible location, this could lead to remote execution of arbitrary
commands with the rights of the HTTP server.


There is no known workaround at this time.


All PHP, mod_php and php-cgi users should upgrade to the latest stable
# emerge sync
# emerge -pv ">=dev-php/php-4.3.9"
# emerge ">=dev-php/php-4.3.9"
# emerge -pv ">=dev-php/mod_php-4.3.9"
# emerge ">=dev-php/mod_php-4.3.9"
# emerge -pv ">=dev-php/php-cgi-4.3.9"
