The Phar extension in PHP before 5.5.34, 5.6.x before 5.6.20, and 7.x before 7.0.5 allows remote attackers to execute arbitrary code via a crafted filename, as demonstrated by mishandling of \0 characters by the phar_analyze_path function in ext/phar/phar.c.

The bcpowmod function in ext/bcmath/bcmath.c in PHP before 5.5.35, 5.6.x before 5.6.21, and 7.x before 7.0.6 accepts a negative integer for the scale argument, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted call.

Format string vulnerability in the php_snmp_error function in ext/snmp/snmp.c in PHP before 5.5.34, 5.6.x before 5.6.20, and 7.x before 7.0.5 allows remote attackers to execute arbitrary code via format string specifiers in an SNMP::get call.

The make_http_soap_request function in ext/soap/php_http.c in PHP before 5.4.44, 5.5.x before 5.5.28, 5.6.x before 5.6.12, and 7.x before 7.0.4 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (type confusion and application crash) via crafted serialized _cookies data, related to the SoapClient::__call method in ext/soap/soap.c.

In PHP versions 8.1.* before 8.1.31, 8.2.* before 8.2.26, 8.3.* before 8.3.14, when using streams with configured proxy and "request_fulluri" option, the URI is not properly sanitized which can lead to HTTP request smuggling and allow the attacker to use the proxy to perform arbitrary HTTP requests originating from the server, thus potentially gaining access to resources not normally available to the external user.

In PHP before 5.5.32, 5.6.x before 5.6.18, and 7.x before 7.0.3, all of the return values of stream_get_meta_data can be controlled if the input can be controlled (e.g., during file uploads). For example, a "$uri = stream_get_meta_data(fopen($file, "r"))['uri']" call mishandles the case where $file is data:text/plain;uri=eviluri, -- in other words, metadata can be set by an attacker.

In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the vulnerability enables network and same-site attackers to set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications.

In PHP before 5.6.28 and 7.x before 7.0.13, incorrect handling of various URI components in the URL parser could be used by attackers to bypass hostname-specific URL checks, as demonstrated by evil.example.com:80#@good.example.com/ and evil.example.com:80?@good.example.com/ inputs to the parse_url function (implemented in the php_url_parse_ex function in ext/standard/url.c).

The odbc_bindcols function in ext/odbc/php_odbc.c in PHP before 5.6.12 mishandles driver behavior for SQL_WVARCHAR columns, which allows remote attackers to cause a denial of service (application crash) in opportunistic circumstances by leveraging use of the odbc_fetch_array function to access a certain type of Microsoft SQL Server table.

The create function in app/code/core/Mage/Catalog/Model/Product/Api/V2.php in Magento Community Edition (CE) before 1.9.2.1 and Enterprise Edition (EE) before 1.14.2.1, when used with PHP before 5.4.24 or 5.5.8, allows remote authenticated users to execute arbitrary PHP code via the productData parameter to index.php/api/v2_soap.

The phar_convert_to_other function in ext/phar/phar_object.c in PHP before 5.4.43, 5.5.x before 5.5.27, and 5.6.x before 5.6.11 does not validate a file pointer before a close operation, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted TAR archive that is mishandled in a Phar::convertToData call.

gd_ctx.c in the GD component in PHP 5.4.x before 5.4.32 and 5.5.x before 5.5.16 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to overwrite arbitrary files via crafted input to an application that calls the (1) imagegd, (2) imagegd2, (3) imagegif, (4) imagejpeg, (5) imagepng, (6) imagewbmp, or (7) imagewebp function.

PHP before 5.4.42, 5.5.x before 5.5.26, and 5.6.x before 5.6.10 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to read or write to arbitrary files via crafted input to an application that calls (1) a DOMDocument save method or (2) the GD imagepsloadfont function, as demonstrated by a filename\0.html attack that bypasses an intended configuration in which client users may write to only .html files.

The mcopy function in softmagic.c in file 5.x, as used in the Fileinfo component in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8, does not properly restrict a certain offset value, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted string that is mishandled by a "Python script text executable" rule.

readelf.c in file before 5.22, as used in the Fileinfo component in PHP before 5.4.37, 5.5.x before 5.5.21, and 5.6.x before 5.6.5, does not consider that pread calls sometimes read only a subset of the available data, which allows remote attackers to cause a denial of service (uninitialized memory access) or possibly have unspecified other impact via a crafted ELF file.

The donote function in readelf.c in file through 5.20, as used in the Fileinfo component in PHP 5.4.34, does not ensure that sufficient note headers are present, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted ELF file.

The cdf_read_property_info function in file before 5.19, as used in the Fileinfo component in PHP before 5.4.30 and 5.5.x before 5.5.14, does not properly validate a stream offset, which allows remote attackers to cause a denial of service (application crash) via a crafted CDF file.

PHP 4.4.x before 4.4.9, and 5.x through 5.2.6, when used as a FastCGI module, allows remote attackers to cause a denial of service (crash) via a request with multiple dots preceding the extension, as demonstrated using foo..php.

In PHP versions 7.3.x below 7.3.29, 7.4.x below 7.4.21 and 8.0.x below 8.0.8, when using URL validation functionality via filter_var() function with FILTER_VALIDATE_URL parameter, an URL with invalid password field can be accepted as valid. This can lead to the code incorrectly parsing the URL and potentially leading to other security implications - like contacting a wrong server or making a wrong access decision.

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.

The iconv_substr function in PHP 5.2.4 and earlier allows context-dependent attackers to cause (1) a denial of service (application crash) via a long string in the charset parameter, probably also requiring a long string in the str parameter; or (2) a denial of service (temporary application hang) via a long string in the str parameter. NOTE: this might not be a vulnerability in most web server environments that support multiple threads, unless these issues can be demonstrated for code execution.

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.

The setlocale function in PHP before 5.2.4 allows context-dependent attackers to cause a denial of service (application crash) via a long string in the locale parameter. 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.

main/streams/xp_socket.c in PHP 7.x before 2017-03-07 misparses fsockopen calls, such as by interpreting fsockopen('127.0.0.1:80', 443) as if the address/port were 127.0.0.1:80:443, which is later truncated to 127.0.0.1:80. This behavior has a security risk if the explicitly provided port number (i.e., 443 in this example) is hardcoded into an application as a security policy, but the hostname argument (i.e., 127.0.0.1:80 in this example) is obtained from untrusted input.

The PDORow implementation in PHP before 5.3.9 does not properly interact with the session feature, which allows remote attackers to cause a denial of service (application crash) via a crafted application that uses a PDO driver for a fetch and then calls the session_start function, as demonstrated by a crash of the Apache HTTP Server.

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when PHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like __Host confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. See also CVE-2020-8184 for more information.

PHP 5.3.8 does not always check the return value of the zend_strndup function, which might allow remote attackers to cause a denial of service (NULL pointer dereference and application crash) via crafted input to an application that performs strndup operations on untrusted string data, as demonstrated by the define function in zend_builtin_functions.c, and unspecified functions in ext/soap/php_sdl.c, ext/standard/syslog.c, ext/standard/browscap.c, ext/oci8/oci8.c, ext/com_dotnet/com_typeinfo.c, and main/php_open_temporary_file.c.

In PHP from 8.1.* before 8.1.32, from 8.2.* before 8.2.28, from 8.3.* before 8.3.19, from 8.4.* before 8.4.5, when user-supplied headers are sent, the insufficient validation of the end-of-line characters may prevent certain headers from being sent or lead to certain headers be misinterpreted.

In PHP from 8.1.* before 8.1.32, from 8.2.* before 8.2.28, from 8.3.* before 8.3.19, from 8.4.* before 8.4.5, when receiving headers from HTTP server, the headers missing a colon (:) are treated as valid headers even though they are not. This may confuse applications into accepting invalid headers.

In PHP from 8.1.* before 8.1.32, from 8.2.* before 8.2.28, from 8.3.* before 8.3.19, from 8.4.* before 8.4.5, when http request module parses HTTP response obtained from a server, folded headers are parsed incorrectly, which may lead to misinterpreting the response and using incorrect headers, MIME types, etc.

Stack consumption vulnerability in Zend/zend_exceptions.c in PHP before 5.4.44, 5.5.x before 5.5.28, and 5.6.x before 5.6.12 allows remote attackers to cause a denial of service (segmentation fault) via recursive method calls.

The mget function in softmagic.c in file 5.x, as used in the Fileinfo component in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8, does not properly maintain a certain pointer relationship, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted string that is mishandled by a "Python script text executable" rule.

The do_soap_call function in ext/soap/soap.c in PHP before 5.4.39, 5.5.x before 5.5.23, and 5.6.x before 5.6.7 does not verify that the uri property is a string, which allows remote attackers to obtain sensitive information by providing crafted serialized data with an int data type, related to a "type confusion" issue.

PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to read or write to arbitrary files via crafted input to an application that calls (1) a DOMDocument load method, (2) the xmlwriter_open_uri function, (3) the finfo_file function, or (4) the hash_hmac_file function, as demonstrated by a filename\0.xml attack that bypasses an intended configuration in which client users may read only .xml files.

The mget function in libmagic/softmagic.c in the Fileinfo component in PHP 5.4.x before 5.4.16 allows remote attackers to cause a denial of service (invalid pointer dereference and application crash) via an MP3 file that triggers incorrect MIME type detection during access to an finfo object.
