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

PHP 5.2.5 and earlier allows context-dependent attackers to cause a denial of service (application crash) via a long string in (1) the domain parameter to the dgettext function, the message parameter to the (2) dcgettext or (3) gettext function, the msgid1 parameter to the (4) dngettext or (5) ngettext function, or (6) the classname parameter to the stream_wrapper_register function. NOTE: this might not be a vulnerability in most web server environments that support multiple threads, unless this issue can be demonstrated for code execution.

PHP before 5.2.5 allows local users to bypass protection mechanisms configured through php_admin_value or php_admin_flag in httpd.conf by using ini_set to modify arbitrary configuration variables, a different issue than CVE-2006-4625.

The (1) htmlentities and (2) htmlspecialchars functions in PHP before 5.2.5 accept partial multibyte sequences, which has unknown impact and attack vectors, a different issue than CVE-2006-5465.

The output_add_rewrite_var function in PHP before 5.2.5 rewrites local forms in which the ACTION attribute references a non-local URL, which allows remote attackers to obtain potentially sensitive information by reading the requests for this URL, as demonstrated by a rewritten form containing a local session ID.

The Component Object Model (COM) functions in PHP 5.x on Windows do not follow safe_mode and disable_functions restrictions, which allows context-dependent attackers to bypass intended limitations, as demonstrated by executing objects with the kill bit set in the corresponding ActiveX control Compatibility Flags, executing programs via a function in compatUI.dll, invoking wscript.shell via wscript.exe, invoking Scripting.FileSystemObject via wshom.ocx, and adding users via a function in shgina.dll, related to the com_load_typelib function.

ioncube_loader_win_5.2.dll in the ionCube Loader 6.5 extension for PHP 5.2.4 does not follow safe_mode and disable_functions restrictions, which allows context-dependent attackers to bypass intended limitations, as demonstrated by reading arbitrary files via the ioncube_read_file function.

The disable_functions feature in PHP 4 and 5 allows attackers to bypass intended restrictions by using an alias, as demonstrated by using ini_alter when ini_set is disabled.

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.

The MySQL extension in PHP 5.2.4 and earlier allows remote attackers to bypass safe_mode and open_basedir restrictions via the MySQL (1) LOAD_FILE, (2) INTO DUMPFILE, and (3) INTO OUTFILE functions, a different issue than CVE-2007-3997.

The dl function in PHP 5.2.4 and earlier allows context-dependent attackers to cause a denial of service (application crash) via a long string in the library parameter. NOTE: there are limited usage scenarios under which this would be a vulnerability.
