Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-2335)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

php-wrapper.fcgi does not properly handle command-line arguments, which allows remote attackers to bypass a protection mechanism in PHP 5.3.12 and 5.4.2 and execute arbitrary code by leveraging improper interaction between the PHP sapi/cgi/cgi_main.c component and a query string beginning with a +- sequence.


2) Input validation error (CVE-ID: CVE-2012-2336)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

sapi/cgi/cgi_main.c in PHP before 5.3.13 and 5.4.x before 5.4.3, when configured as a CGI script (aka php-cgi), does not properly handle query strings that lack an = (equals sign) character, which allows remote attackers to cause a denial of service (resource consumption) by placing command-line options in the query string, related to lack of skipping a certain php_getopt for the 'T' case. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1823.
