CVE-2003-0861 1 Php 1 Php 2025-04-03 10.0 HIGH N/A
Integer overflows in (1) base64_encode and (2) the GD library for PHP before 4.3.3 have unknown impact and unknown attack vectors.
CVE-2006-3017 1 Php 1 Php 2025-04-03 9.3 HIGH N/A
zend_hash_del_key_or_index in zend_hash.c in PHP before 4.4.3 and 5.x before 5.1.3 can cause zend_hash_del to delete the wrong element, which prevents a variable from being unset even when the PHP unset function is called, which might cause the variable's value to be used in security-relevant operations.
CVE-2006-0207 1 Php 1 Php 2025-04-03 5.0 MEDIUM N/A
Multiple HTTP response splitting vulnerabilities in PHP 5.1.1 allow remote attackers to inject arbitrary HTTP headers via a crafted Set-Cookie header, related to the (1) session extension (aka ext/session) and the (2) header function.
CVE-2003-0249 1 Php 1 Php 2025-04-03 7.5 HIGH N/A
PHP treats unknown methods such as "PoSt" as a GET request, which could allow attackers to intended access restrictions if PHP is running on a server that passes on all methods, such as Apache httpd 2.0, as demonstrated using a Limit directive. NOTE: this issue has been disputed by the Apache security team, saying "It is by design that PHP allows scripts to process any request method. A script which does not explicitly verify the request method will hence be processed as normal for arbitrary methods. It is therefore expected behaviour that one cannot implement per-method access control using the Apache configuration alone, which is the assumption made in this report.
CVE-2004-1018 2 Canonical, Php 2 Ubuntu Linux, Php 2025-04-03 10.0 HIGH N/A
Multiple integer handling errors in PHP before 4.3.10 allow attackers to bypass safe mode restrictions, cause a denial of service, or execute arbitrary code via (1) a negative offset value to the shmop_write function, (2) an "integer overflow/underflow" in the pack function, or (3) an "integer overflow/underflow" in the unpack function. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.
CVE-2002-0484 1 Php 1 Php 2025-04-03 5.0 MEDIUM N/A
move_uploaded_file in PHP does not does not check for the base directory (open_basedir), which could allow remote attackers to upload files to unintended locations on the system.
CVE-2006-4023 1 Php 1 Php 2025-04-03 5.0 MEDIUM 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.
CVE-2000-0860 1 Php 1 Php 2025-04-03 5.0 MEDIUM N/A
The file upload capability in PHP versions 3 and 4 allows remote attackers to read arbitrary files by setting hidden form fields whose names match the names of internal PHP script variables.
CVE-2005-3391 1 Php 1 Php 2025-04-03 7.5 HIGH N/A
Multiple vulnerabilities in PHP before 4.4.1 allow remote attackers to bypass safe_mode and open_basedir restrictions via unknown attack vectors in (1) ext/curl and (2) ext/gd.
CVE-2005-1043 6 Apple, Conectiva, Peachtree and 3 more 7 Mac Os X, Mac Os X Server, Linux and 4 more 2025-04-03 5.0 MEDIUM N/A
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.
CVE-2003-0097 1 Php 1 Php 2025-04-03 7.5 HIGH N/A
Unknown vulnerability in CGI module for PHP 4.3.0 allows attackers to access arbitrary files as the PHP user, and possibly execute PHP code, by bypassing the CGI force redirect settings (cgi.force_redirect or --enable-force-cgi-redirect).
CVE-2003-1302 1 Php 1 Php 2025-04-03 5.0 MEDIUM N/A
The IMAP functionality in PHP before 4.3.1 allows remote attackers to cause a denial of service via an e-mail message with a (1) To or (2) From header with an address that contains a large number of "\" (backslash) characters.
CVE-2002-0253 1 Php 1 Php 2025-04-03 5.0 MEDIUM N/A
PHP, when not configured with the "display_errors = Off" setting in php.ini, allows remote attackers to obtain the physical path for an include file via a trailing slash in a request to a directly accessible PHP program, which modifies the base path, causes the include directive to fail, and produces an error message that contains the path.
CVE-2004-1019 4 Openpkg, Php, Trustix and 1 more 4 Openpkg, Php, Secure Linux and 1 more 2025-04-03 10.0 HIGH N/A
The deserialization code in PHP before 4.3.10 and PHP 5.x up to 5.0.2 allows remote attackers to cause a denial of service and execute arbitrary code via untrusted data to the unserialize function that may trigger "information disclosure, double-free and negative reference index array underflow" results.
CVE-2006-4433 1 Php 1 Php 2025-04-03 7.5 HIGH 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-2004-0594 6 Avaya, Debian, Hp and 3 more 6 Converged Communications Server, Debian Linux, Hp-ux and 3 more 2025-04-03 5.1 MEDIUM N/A
The memory_limit functionality in PHP 4.x up to 4.3.7, and 5.x up to 5.0.0RC3, under certain conditions such as when register_globals is enabled, allows remote attackers to execute arbitrary code by triggering a memory_limit abort during execution of the zend_hash_init function and overwriting a HashTable destructor pointer before the initialization of key data structures is complete.
CVE-2006-1494 1 Php 1 Php 2025-04-03 2.6 LOW N/A
Directory traversal vulnerability in file.c in PHP 4.4.2 and 5.1.2 allows local users to bypass open_basedir restrictions allows remote attackers to create files in arbitrary directories via the tempnam function.
CVE-2003-1303 1 Php 1 Php 2025-04-03 5.0 MEDIUM N/A
Buffer overflow in the imap_fetch_overview function in the IMAP functionality (php_imap.c) in PHP before 4.3.3 allows remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a long e-mail address in a (1) To or (2) From header.
CVE-2002-0229 1 Php 1 Php 2025-04-03 7.5 HIGH N/A
Safe Mode feature (safe_mode) in PHP 3.0 through 4.1.0 allows attackers with access to the MySQL database to bypass Safe Mode access restrictions and read arbitrary files using "LOAD DATA INFILE LOCAL" SQL statements.
CVE-2002-1396 1 Php 1 Php 2025-04-03 7.5 HIGH N/A
Heap-based buffer overflow in the wordwrap function in PHP after 4.1.2 and before 4.3.0 may allow attackers to cause a denial of service or execute arbitrary code.
