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 mapping's 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.
A flaw was found in the way PHP handled malformed source files when running in CGI mode. A specially crafted PHP file could cause PHP CGI to crash.
Отчет
This flaw requires that a user is able to upload arbitrary PHP code on the system, be a local user able to execute arbitrary PHP code, or have the ability to modify existing PHP code on the system. It also requires that the modified/arbitrary PHP code is executed with the php-cgi program, and the net result is that php-cgi crashes, effectively resulting in a self-denial of service. Red Hat Product Security has rated this issue as having Low security impact. This issue is not currently planned to be addressed in future updates.
