CVE-2007-1522 1 Php 1 Php 2026-04-23 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.
CVE-2007-1396 1 Php 1 Php 2026-04-23 N/A
The import_request_variables function in PHP 4.0.7 through 4.4.6, and 5.x before 5.2.2, when called without a prefix, does not prevent the (1) GET, (2) POST, (3) COOKIE, (4) FILES, (5) SERVER, (6) SESSION, and other superglobals from being overwritten, which allows remote attackers to spoof source IP address and Referer data, and have other unspecified impact. NOTE: it could be argued that this is a design limitation of PHP and that only the misuse of this feature, i.e. implementation bugs in applications, should be included in CVE. However, it has been fixed by the vendor.
CVE-2007-1581 1 Php 1 Php 2026-04-23 N/A
The resource system in PHP 5.0.0 through 5.2.1 allows context-dependent attackers to execute arbitrary code by interrupting the hash_update_file function via a userspace (1) error or (2) stream handler, which can then be used to destroy and modify internal resources. NOTE: it was later reported that PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 are also affected.
CVE-2007-1825 2 Php, Redhat 4 Php, Enterprise Linux, Rhel Application Stack and 1 more 2026-04-23 N/A
Buffer overflow in the imap_mail_compose function in PHP 5 before 5.2.1, and PHP 4 before 4.4.5, allows remote attackers to execute arbitrary code via a long boundary string in a type.parameters field. NOTE: as of 20070411, it appears that this issue might be subsumed by CVE-2007-0906.3.
CVE-2007-1454 1 Php 1 Php 2026-04-23 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-2008-2371 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-04-23 N/A
Heap-based buffer overflow in pcre_compile.c in the Perl-Compatible Regular Expression (PCRE) library 7.7 allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a regular expression that begins with an option and contains multiple branches.
CVE-2009-4143 1 Php 1 Php 2026-04-23 N/A
PHP before 5.2.12 does not properly handle session data, which has unspecified impact and attack vectors related to (1) interrupt corruption of the SESSION superglobal array and (2) the session.save_path directive.
CVE-2007-1583 2 Php, Redhat 3 Php, Enterprise Linux, Rhel Application Stack 2026-04-23 N/A
The mb_parse_str function in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 sets the internal register_globals flag and does not disable it in certain cases when a script terminates, which allows remote attackers to invoke available PHP scripts with register_globals functionality that is not detectable by these scripts, as demonstrated by forcing a memory_limit violation.
CVE-2007-1864 4 Canonical, Debian, Php and 1 more 7 Ubuntu Linux, Debian Linux, Php and 4 more 2026-04-23 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-2008-3658 2 Php, Redhat 2 Php, Enterprise Linux 2026-04-23 N/A
Buffer overflow in the imageloadfont function in ext/gd/gd.c in PHP 4.4.x before 4.4.9 and PHP 5.2 before 5.2.6-r6 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted font file.
CVE-2009-3559 1 Php 1 Php 2026-04-23 N/A
main/streams/plain_wrapper.c in PHP 5.3.x before 5.3.1 does not recognize the safe_mode_include_dir directive, which allows context-dependent attackers to have an unknown impact by triggering the failure of PHP scripts that perform include or require operations, as demonstrated by a script that attempts to perform a require_once on a file in a standard library directory. NOTE: a reliable third party reports that this is not a vulnerability, because it results in a more restrictive security policy.
CVE-2009-2626 1 Php 1 Php 2026-04-23 N/A
The zend_restore_ini_entry_cb function in zend_ini.c in PHP 5.3.0, 5.2.10, and earlier versions allows context-specific attackers to obtain sensitive information (memory contents) and cause a PHP crash by using the ini_set function to declare a variable, then using the ini_restore function to restore the variable.
CVE-2009-3293 1 Php 1 Php 2026-04-23 N/A
Unspecified vulnerability in the imagecolortransparent function in PHP before 5.2.11 has unknown impact and attack vectors related to an incorrect "sanity check for the color index."
CVE-2012-1823 8 Apple, Debian, Fedoraproject and 5 more 20 Mac Os X, Debian Linux, Fedora and 17 more 2026-04-21 9.8 Critical
sapi/cgi/cgi_main.c in PHP before 5.3.12 and 5.4.x before 5.4.2, when configured as a CGI script (aka php-cgi), does not properly handle query strings that lack an = (equals sign) character, which allows remote attackers to execute arbitrary code by placing command-line options in the query string, related to lack of skipping a certain php_getopt for the 'd' case.
CVE-2004-1392 2 Php, Redhat 2 Php, Enterprise Linux 2026-04-16 N/A
PHP 4.0 with cURL functions allows remote attackers to bypass the open_basedir setting and read arbitrary files via a file: URL argument to the curl_init function.
CVE-2002-2309 1 Php 1 Php 2026-04-16 N/A
php.exe in PHP 3.0 through 4.2.2, when running on Apache, does not terminate properly, which allows remote attackers to cause a denial of service via a direct request without arguments.
CVE-2005-1042 2 Php, Redhat 2 Php, Enterprise Linux 2026-04-16 N/A
Integer overflow in the exif_process_IFD_TAG function in exif.c in PHP before 4.3.11 may allow remote attackers to execute arbitrary code via an IFD tag that leads to a negative byte count.
CVE-2000-0059 1 Php 1 Php 2026-04-16 N/A
PHP3 with safe_mode enabled does not properly filter shell metacharacters from commands that are executed by popen, which could allow remote attackers to execute commands.
CVE-2006-4433 1 Php 1 Php 2026-04-16 N/A
PHP before 4.4.3 and 5.x before 5.1.4 does not limit the character set of the session identifier (PHPSESSID) for third party session handlers, which might make it easier for remote attackers to exploit other vulnerabilities by inserting PHP code into the PHPSESSID, which is stored in the session file. NOTE: it could be argued that this not a vulnerability in PHP itself, rather a design limitation that enables certain attacks against session handlers that do not account for this limitation.
CVE-2006-4023 1 Php 1 Php 2026-04-16 N/A
The ip2long function in PHP 5.1.4 and earlier may incorrectly validate an arbitrary string and return a valid network IP address, which allows remote attackers to obtain network information and facilitate other attacks, as demonstrated using SQL injection in the X-FORWARDED-FOR Header in index.php in MiniBB 2.0. NOTE: it could be argued that the ip2long behavior represents a risk for security-relevant issues in a way that is similar to strcpy's role in buffer overflows, in which case this would be a class of implementation bugs that would require separate CVE items for each PHP application that uses ip2long in a security-relevant manner.
