Description:
Some vulnerabilities have been reported in PHP, which can be exploited by malicious people to conduct cross-site scripting attacks, bypass certain security restrictions, and potentially compromise a vulnerable system.
1) An error where the "GLOBALS" array is not properly protected, can be exploited to define global variables by sending a "multipart/form-data" POST request with a specially crafted file upload field, or via a script calling the PHP function "extract()" or "import_request_variables()".
Successful exploitation may open up for vulnerabilities in various applications, but requires that "register_globals" is enabled.
2) An error in the handling of an unexpected termination in the "parse_str()" PHP function, can be exploited to enable the "register_globals" directive for the current execution by e.g. triggering a memory_limit request shutdown in a script calling "parse_str()".
3) Some unspecified input passed to the "phpinfo()" PHP function isn't properly sanitised before being returned to the user. This can be exploited via a script calling "phpinfo()" to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
4) An integer overflow error in pcrelib may be exploited to cause a memory corruption via a script calling a PHP function using the PCRE library where the regular expression can be controlled by the attacker.
For more information:
SA16502
Successful exploitation may allow execution of arbitrary code.
5) The problem is that it is possible to bypass the "safe_mode" and "open_basedir" protection mechanisms via the "ext/curl" and "ext/gd" modules.
6) An unspecified error in calling "virtual()" on Apache 2 can be exploited to bypass certain configuration directives (e.g. "safe_mode" and "open_basedir").
Other bugs have also been reported where some may be security related.
The vulnerabilities have been reported in versions 4.4.0 and 5.0.5. Prior versions may also be affected.
