PHP — популярный язык сценариев общего назначения, особенно подходящий для веб-разработки.

exif.c in PHP before 4.3.11 allows remote attackers to cause a denial of service (memory consumption and crash) via an EXIF header with a large IFD nesting level, which causes significant stack recursion.

Integer overflow in the msg_receive function in PHP 4 before 4.4.5 and PHP 5 before 5.2.1, on FreeBSD and possibly other platforms, allows context-dependent attackers to execute arbitrary code via certain maxsize values, as demonstrated by 0xffffffff.

The cpdf_open function in the ClibPDF (cpdf) extension in PHP 4.4.6 allows context-dependent attackers to obtain sensitive information (script source code) via a long string in the second argument.

A regression error in the phpinfo function in PHP 4.4.3 to 4.4.6, and PHP 6.0 in CVS, allows remote attackers to conduct cross-site scripting (XSS) attacks via GET, POST, or COOKIE array values, which are not escaped in the phpinfo output, as originally fixed for CVE-2005-3388.

SimpNews 2.41.03 on Windows, when PHP before 5.0.0 is used, allows remote attackers to obtain sensitive information via an certain link_date parameter to events.php, which reveals the path in an error message due to an unsupported argument type for the mktime function on Windows.

Unspecified vulnerability in PHP before 5.2.4 has unknown impact and attack vectors, related to an "Improved fix for MOPB-03-2007," probably a variant of CVE-2007-1285.

fopen_wrappers.c in PHP 4.4.0, and possibly other versions, does not properly restrict access to other directories when the open_basedir directive includes a trailing slash, which allows PHP scripts in one directory to access files in other directories whose names are substrings of the original directory.

Race condition in the symlink function in PHP 5.1.6 and earlier allows local users to bypass the open_basedir restriction by using a combination of symlink, mkdir, and unlink functions to change the file path after the open_basedir check and before the file is opened by the underlying system, as demonstrated by symlinking a symlink into a subdirectory, to point to a parent directory via .. (dot dot) sequences, and then unlinking the resulting symlink.

The apache2handler SAPI (sapi_apache2.c) in the Apache module (mod_php) for PHP 5.x before 5.1.0 final and 4.4 before 4.4.1 final allows attackers to cause a denial of service (segmentation fault) via the session.save_path option in a .htaccess file or VirtualHost.

PHP before 5.3.4 accepts the \0 character in a pathname, which might allow context-dependent attackers to bypass intended access restrictions by placing a safe file extension after this character, as demonstrated by .php\0.jpg at the end of the argument to the file_exists function.
