Title: PHP Improper Restriction of Operations within the Bounds of a Memory Buffer Vulnerability

Overview:

sapi/cgi/cgi_main.c in the CGI component in PHP through 5.4.36 5.5.x through 5.5.20 and 5.6.x through 5.6.4 when mmap is used to read a .php file does not properly consider the mapping39s length during processing of an invalid file that begins with a character and lacks a newline character which causes an out-of-bounds read and might (1) allow remote attackers to obtain sensitive information from php-cgi process memory by leveraging the ability to upload a .php file or (2) trigger unexpected code execution if a valid PHP script is present in memory locations adjacent to the mapping.
