PHP 5.3 < 5.3.1 Multiple Vulnerabilities

medium Nessus Plugin ID 42862

Synopsis

The remote web server uses a version of PHP that is affected by multiple flaws.

Description

According to its banner, the version of PHP 5.3 installed on the remote host is older than 5.3.1. Such versions may be affected by several security issues :

- Sanity checks are missing in exif processing.

- It is possible to bypass the 'safe_mode' configuration setting using 'tempnam()'.

- It is possible to bypass the 'open_basedir' configuration setting using 'posix_mkfifo()'.

- The 'safe_mode_include_dir' configuration setting may be ignored. (Bug #50063)

- Calling 'popen()' with an invalid mode can cause a crash under Windows. (Bug #44683)

- Provided file uploading is enabled (it is by default), an attacker can upload files using a POST request with 'multipart/form-data' content even if the target script doesn't actually support file uploads per se. By supplying a large number (15,000+) of files, an attacker could cause the web server to stop responding while it processes the file list.

- 'proc_open()' can bypass 'safe_mode_protected_env_vars'.
(Bug #49026)

- An unspecified vulnerability affects the LCG entropy.

Solution

Upgrade to PHP version 5.3.1 or later.
