sol17313: PHP vulnerability CVE-2014-4721
Security Advisory
Original Publication Date: 09/23/2015
Description
The phpinfo implementation in ext/standard/info.c in PHP before 5.4.30 and
5.5.x before 5.5.14 does not ensure use of the string data type for the
PHP_AUTH_PW, PHP_AUTH_TYPE, PHP_AUTH_USER, and PHP_SELF variables, which might
allow context-dependent attackers to obtain sensitive information from process
memory by using the integer data type with crafted values, related to a "type
confusion" vulnerability, as demonstrated by reading a private SSL key in an
Apache HTTP Server web-hosting environment with mod_ssl and a PHP 5.3.x
mod_php. (CVE-2014-4721)
Impact
This vulnerability allows the unauthorized disclosure of information.
