CVE-2009-3294 2 Microsoft, Php 4 Windows 7, Windows Server 2008, Windows Xp and 1 more 2026-04-23 5.0 MEDIUM N/A
The popen API function in TSRM/tsrm_win32.c in PHP before 5.2.11 and 5.3.x before 5.3.1, when running on certain Windows operating systems, allows context-dependent attackers to cause a denial of service (crash) via a crafted (1) "e" or (2) "er" string in the second argument (aka mode), possibly related to the _fdopen function in the Microsoft C runtime library. NOTE: this might not cross privilege boundaries except in rare cases in which the mode argument is accessible to an attacker outside of an application that uses the popen function.
CVE-2006-5465 1 Php 1 Php 2026-04-23 7.5 HIGH N/A
Buffer overflow in PHP before 5.2.0 allows remote attackers to execute arbitrary code via crafted UTF-8 inputs to the (1) htmlentities or (2) htmlspecialchars functions.
CVE-2009-4418 1 Php 1 Php 2026-04-23 5.0 MEDIUM N/A
The unserialize function in PHP 5.3.0 and earlier allows context-dependent attackers to cause a denial of service (resource consumption) via a deeply nested serialized variable, as demonstrated by a string beginning with a:1: followed by many {a:1: sequences.
CVE-2007-2748 1 Php 1 Php 2026-04-23 4.3 MEDIUM N/A
The substr_count function in PHP 5.2.1 and earlier allows context-dependent attackers to obtain sensitive information via unspecified vectors, a different affected function than CVE-2007-1375.
CVE-2007-2369 2 Php, Webspell 2 Php, Webspell 2026-04-23 5.0 MEDIUM N/A
Directory traversal vulnerability in picture.php in WebSPELL 4.01.02 and earlier, when PHP before 4.3.0 is used, allows remote attackers to read arbitrary files via a .. (dot dot) in the id parameter.
CVE-2007-4660 1 Php 1 Php 2026-04-23 7.5 HIGH N/A
Unspecified vulnerability in the chunk_split function in PHP before 5.2.4 has unknown impact and attack vectors, related to an incorrect size calculation.
CVE-2007-4596 1 Php 1 Php 2026-04-23 7.5 HIGH N/A
The perl extension in PHP does not follow safe_mode restrictions, which allows context-dependent attackers to execute arbitrary code via the Perl eval function. NOTE: this might only be a vulnerability in limited environments.
CVE-2007-1864 4 Canonical, Debian, Php and 1 more 5 Ubuntu Linux, Debian Linux, Php and 2 more 2026-04-23 7.5 HIGH N/A
Buffer overflow in the bundled libxmlrpc library in PHP before 4.4.7, and 5.x before 5.2.2, has unknown impact and remote attack vectors.
CVE-2007-1454 1 Php 1 Php 2026-04-23 4.3 MEDIUM N/A
ext/filter in PHP 5.2.0, when FILTER_SANITIZE_STRING is used with the FILTER_FLAG_STRIP_LOW flag, does not properly strip HTML tags, which allows remote attackers to conduct cross-site scripting (XSS) attacks via HTML with a '<' character followed by certain whitespace characters, which passes one filter but is collapsed into a valid tag, as demonstrated using %0b.
CVE-2007-1375 1 Php 1 Php 2026-04-23 5.0 MEDIUM N/A
Integer overflow in the substr_compare function in PHP 5.2.1 and earlier allows context-dependent attackers to read sensitive memory via a large value in the length argument, a different vulnerability than CVE-2006-1991.
CVE-2007-3378 1 Php 1 Php 2026-04-23 6.8 MEDIUM N/A
The (1) session_save_path, (2) ini_set, and (3) error_log functions in PHP 4.4.7 and earlier, and PHP 5 5.2.3 and earlier, when invoked from a .htaccess file, allow remote attackers to bypass safe_mode and open_basedir restrictions and possibly execute arbitrary commands, as demonstrated using (a) php_value, (b) php_flag, and (c) directives in .htaccess.
CVE-2007-3007 1 Php 1 Php 2026-04-23 5.0 MEDIUM N/A
PHP 5 before 5.2.3 does not enforce the open_basedir or safe_mode restriction in certain cases, which allows context-dependent attackers to determine the existence of arbitrary files by checking if the readfile function returns a string. NOTE: this issue might also involve the realpath function.
CVE-2007-5424 1 Php 1 Php 2026-04-23 7.5 HIGH N/A
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.
CVE-2007-4441 1 Php 1 Php 2026-04-23 4.6 MEDIUM N/A
Buffer overflow in php_win32std.dll in the win32std extension for PHP 5.2.0 and earlier allows context-dependent attackers to execute arbitrary code via a long string in the filename argument to the win_browse_file function.
CVE-2008-0599 4 Apple, Canonical, Fedoraproject and 1 more 5 Mac Os X, Mac Os X Server, Ubuntu Linux and 2 more 2026-04-23 10.0 HIGH 9.8 CRITICAL
The init_request_info function in sapi/cgi/cgi_main.c in PHP before 5.2.6 does not properly consider operator precedence when calculating the length of PATH_TRANSLATED, which might allow remote attackers to execute arbitrary code via a crafted URI.
CVE-2007-1584 1 Php 1 Php 2026-04-23 6.8 MEDIUM N/A
Buffer underflow in the header function in PHP 5.2.0 allows context-dependent attackers to execute arbitrary code by passing an all-whitespace string to this function, which causes it to write '\0' characters in whitespace that precedes the string.
CVE-2008-5624 1 Php 1 Php 2026-04-23 7.5 HIGH N/A
PHP 5 before 5.2.7 does not properly initialize the page_uid and page_gid global variables for use by the SAPI php_getuid function, which allows context-dependent attackers to bypass safe_mode restrictions via variable settings that are intended to be restricted to root, as demonstrated by a setting of /etc for the error_log variable.
CVE-2007-4507 1 Php 1 Php 2026-04-23 6.8 MEDIUM N/A
Multiple buffer overflows in the php_ntuser component for PHP 5.2.3 allow context-dependent attackers to cause a denial of service or execute arbitrary code via long arguments to the (1) ntuser_getuserlist, (2) ntuser_getuserinfo, (3) ntuser_getusergroups, or (4) ntuser_getdomaincontroller functions.
CVE-2007-1700 1 Php 1 Php 2026-04-23 7.5 HIGH N/A
The session extension in PHP 4 before 4.4.5, and PHP 5 before 5.2.1, calculates the reference count for the session variables without considering the internal pointer from the session globals, which allows context-dependent attackers to execute arbitrary code via a crafted string in the session_register after unsetting HTTP_SESSION_VARS and _SESSION, which destroys the session data Hashtable.
CVE-2007-1522 1 Php 1 Php 2026-04-23 6.8 MEDIUM N/A
Double free vulnerability in the session extension in PHP 5.2.0 and 5.2.1 allows context-dependent attackers to execute arbitrary code via illegal characters in a session identifier, which is rejected by an internal session storage module, which calls the session identifier generator with an improper environment, leading to code execution when the generator is interrupted, as demonstrated by triggering a memory limit violation or certain PHP errors.
