CVE-2026-6104 2 Php, Php Group 2 Php, Php 2026-05-12 9.1 Critical
In PHP versions 8.4.* before 8.4.21 and 8.5.* before 8.5.6, when an encoding name containing an embedded NUL byte is passed to mb_convert_encoding() or related mbstring functions, the code incorrectly assumes that when strncasecmp() returns 0 it means the strings have the same length. This can lead to out-of-bounds read of global memory, potentially causing a crash or information disclosure or crash. Affected functions include mb_convert_encoding(), mb_detect_encoding(), mb_convert_variables(), and mb_detect_order(), as well as the mbstring.detect_order and mbstring.http_output INI settings.
CVE-2026-7263 2 Php, Php Group 2 Php, Php 2026-05-12 7.5 High
In PHP versions 8.4.* before 8.4.21 and 8.5.* before 8.5.6, DOMNode::C14N() method may process the XML data incorrectly, causing a circular linked list in the data structure representing the XML document. This may cause subsequent processing of the XML document to enter infinite loop, causing denial of service in the processing application.
CVE-2009-3546 3 Libgd, Php, Redhat 3 Gd Graphics Library, Php, Enterprise Linux 2026-04-23 N/A
The _gdGetColors function in gd_gd.c in PHP 5.2.11 and 5.3.x before 5.3.1, and the GD Graphics Library 2.x, does not properly verify a certain colorsTotal structure member, which might allow remote attackers to conduct buffer overflow or buffer over-read attacks via a crafted GD file, a different vulnerability than CVE-2009-3293. NOTE: some of these details are obtained from third party information.
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-2007-0455 5 Canonical, Fedoraproject, Gd Graphics Library Project and 2 more 9 Ubuntu Linux, Fedora, Gd Graphics Library and 6 more 2026-04-23 N/A
Buffer overflow in the gdImageStringFTEx function in gdft.c in GD Graphics Library 2.0.33 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted string with a JIS encoded font.
CVE-2007-0988 3 Canonical, Php, Redhat 5 Ubuntu Linux, Php, Enterprise Linux and 2 more 2026-04-23 N/A
The zend_hash_init function in PHP 5 before 5.2.1 and PHP 4 before 4.4.5, when running on a 64-bit platform, allows context-dependent attackers to cause a denial of service (infinite loop) by unserializing certain integer expressions, which only cause 32-bit arguments to be used after the check for a negative value, as demonstrated by an "a:2147483649:{" argument.
CVE-2006-6545 1 Php 1 Errordocs 2026-04-23 N/A
PHP remote file inclusion vulnerability in includes/common.php in the ErrorDocs 1.0.0 and earlier module for mxBB (mx_errordocs) allows remote attackers to execute arbitrary PHP code via a URL in the module_root_path parameter.
CVE-2007-0905 2 Php, Trustix 2 Php, Secure Linux 2026-04-23 N/A
PHP before 5.2.1 allows attackers to bypass safe_mode and open_basedir restrictions via unspecified vectors in the session extension. NOTE: it is possible that this issue is a duplicate of CVE-2006-6383.
CVE-2007-0906 3 Php, Redhat, Trustix 5 Php, Enterprise Linux, Rhel Application Stack and 2 more 2026-04-23 N/A
Multiple buffer overflows in PHP before 5.2.1 allow attackers to cause a denial of service and possibly execute arbitrary code via unspecified vectors in the (1) session, (2) zip, (3) imap, and (4) sqlite extensions; (5) stream filters; and the (6) str_replace, (7) mail, (8) ibase_delete_user, (9) ibase_add_user, and (10) ibase_modify_user functions. NOTE: vector 6 might actually be an integer overflow (CVE-2007-1885). NOTE: as of 20070411, vector (3) might involve the imap_mail_compose function (CVE-2007-1825).
CVE-2007-0907 3 Php, Redhat, Trustix 5 Php, Enterprise Linux, Rhel Application Stack and 2 more 2026-04-23 N/A
Buffer underflow in PHP before 5.2.1 allows attackers to cause a denial of service via unspecified vectors involving the sapi_header_op function.
CVE-2007-0908 3 Canonical, Php, Redhat 5 Ubuntu Linux, Php, Enterprise Linux and 2 more 2026-04-23 N/A
The WDDX deserializer in the wddx extension in PHP 5 before 5.2.1 and PHP 4 before 4.4.5 does not properly initialize the key_length variable for a numerical key, which allows context-dependent attackers to read stack memory via a wddxPacket element that contains a variable with a string name before a numerical variable.
CVE-2007-0909 3 Php, Redhat, Trustix 5 Php, Enterprise Linux, Rhel Application Stack and 2 more 2026-04-23 N/A
Multiple format string vulnerabilities in PHP before 5.2.1 might allow attackers to execute arbitrary code via format string specifiers to (1) all of the *print functions on 64-bit systems, and (2) the odbc_result_all function.
CVE-2007-0910 3 Php, Redhat, Trustix 5 Php, Enterprise Linux, Rhel Application Stack and 2 more 2026-04-23 N/A
Unspecified vulnerability in PHP before 5.2.1 allows attackers to "clobber" certain super-global variables via unspecified vectors.
CVE-2007-0911 1 Php 1 Php 2026-04-23 N/A
Off-by-one error in the str_ireplace function in PHP 5.2.1 might allow context-dependent attackers to cause a denial of service (crash).
CVE-2007-2727 1 Php 1 Php 2026-04-23 N/A
The mcrypt_create_iv function in ext/mcrypt/mcrypt.c in PHP before 4.4.7, 5.2.1, and possibly 5.0.x and other PHP 5 versions, calls php_rand_r with an uninitialized seed variable and therefore always generates the same initialization vector (IV), which might allow context-dependent attackers to decrypt certain data more easily because of the guessable encryption keys.
CVE-2006-5465 2 Php, Redhat 4 Php, Enterprise Linux, Rhel Application Stack and 1 more 2026-04-23 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-2007-1285 5 Canonical, Novell, Php and 2 more 10 Ubuntu Linux, Suse Linux, Php and 7 more 2026-04-23 7.5 High
The Zend Engine in PHP 4.x before 4.4.7, and 5.x before 5.2.2, allows remote attackers to cause a denial of service (stack exhaustion and PHP crash) via deeply nested arrays, which trigger deep recursion in the variable destruction routines.
CVE-2006-4812 2 Php, Redhat 3 Php, Enterprise Linux, Rhel Application Stack 2026-04-23 N/A
Integer overflow in PHP 5 up to 5.1.6 and 4 before 4.3.0 allows remote attackers to execute arbitrary code via an argument to the unserialize PHP function with a large value for the number of array elements, which triggers the overflow in the Zend Engine ecalloc function (Zend/zend_alloc.c).
CVE-2009-4418 1 Php 1 Php 2026-04-23 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-2009-4017 4 Apple, Debian, Php and 1 more 4 Mac Os X, Debian Linux, Php and 1 more 2026-04-23 N/A
PHP before 5.2.12 and 5.3.x before 5.3.1 does not restrict the number of temporary files created when handling a multipart/form-data POST request, which allows remote attackers to cause a denial of service (resource exhaustion), and makes it easier for remote attackers to exploit local file inclusion vulnerabilities, via multiple requests, related to lack of support for the max_file_uploads directive.
