CVE-2017-12933 1 Php 1 Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
The finish_nested_data function in ext/standard/var_unserializer.re in PHP before 5.6.31, 7.0.x before 7.0.21, and 7.1.x before 7.1.7 is prone to a buffer over-read while unserializing untrusted data. Exploitation of this issue can have an unspecified impact on the integrity of PHP.
CVE-2017-9227 2 Oniguruma Project, Php 2 Oniguruma, Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds read occurs in mbc_enc_len() during regular expression searching. Invalid handling of reg->dmin in forward_search_range() could result in an invalid pointer dereference, as an out-of-bounds read from a stack buffer.
CVE-2017-16642 4 Canonical, Debian, Netapp and 1 more 5 Ubuntu Linux, Debian Linux, Clustered Data Ontap and 2 more 2025-04-20 5.0 MEDIUM 7.5 HIGH
In PHP before 5.6.32, 7.x before 7.0.25, and 7.1.x before 7.1.11, an error in the date extension's timelib_meridian handling of 'front of' and 'back of' directives could be used by attackers able to supply date strings to leak information from the interpreter, related to ext/date/lib/parse_date.c out-of-bounds reads affecting the php_parse_date function. NOTE: this is a different issue than CVE-2017-11145.
CVE-2017-11145 1 Php 1 Php 2025-04-20 5.0 MEDIUM 7.5 HIGH
In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x before 7.1.7, an error in the date extension's timelib_meridian parsing code could be used by attackers able to supply date strings to leak information from the interpreter, related to ext/date/lib/parse_date.c out-of-bounds reads affecting the php_parse_date function. NOTE: the correct fix is in the e8b7698f5ee757ce2c8bd10a192a491a498f891c commit, not the bd77ac90d3bdf31ce2a5251ad92e9e75 gist.
CVE-2017-7890 1 Php 1 Php 2025-04-20 4.3 MEDIUM 6.5 MEDIUM
The GIF decoding function gdImageCreateFromGifCtx in gd_gif_in.c in the GD Graphics Library (aka libgd), as used in PHP before 5.6.31 and 7.x before 7.1.7, does not zero colorMap arrays before use. A specially crafted GIF image could use the uninitialized tables to read ~700 bytes from the top of the stack, potentially disclosing sensitive information.
CVE-2017-8923 1 Php 1 Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
The zend_string_extend function in Zend/zend_string.h in PHP through 7.1.5 does not prevent changes to string objects that result in a negative length, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact by leveraging a script's use of .= with a long string.
CVE-2017-12932 1 Php 1 Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
ext/standard/var_unserializer.re in PHP 7.0.x through 7.0.22 and 7.1.x through 7.1.8 is prone to a heap use after free while unserializing untrusted data, related to improper use of the hash API for key deletion in a situation with an invalid array size. Exploitation of this issue can have an unspecified impact on the integrity of PHP.
CVE-2016-5399 1 Php 1 Php 2025-04-20 6.8 MEDIUM 7.8 HIGH
The bzread function in ext/bz2/bz2.c in PHP before 5.5.38, 5.6.x before 5.6.24, and 7.x before 7.0.9 allows remote attackers to cause a denial of service (out-of-bounds write) or execute arbitrary code via a crafted bz2 archive.
CVE-2016-10397 1 Php 1 Php 2025-04-20 5.0 MEDIUM 7.5 HIGH
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).
CVE-2017-11142 1 Php 1 Php 2025-04-20 7.8 HIGH 7.5 HIGH
In PHP before 5.6.31, 7.x before 7.0.17, and 7.1.x before 7.1.3, remote attackers could cause a CPU consumption denial of service attack by injecting long form variables, related to main/php_variables.c.
CVE-2016-7480 2 Netapp, Php 2 Clustered Data Ontap, Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
The SplObjectStorage unserialize implementation in ext/spl/spl_observer.c in PHP before 7.0.12 does not verify that a key is an object, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized memory access) via crafted serialized data.
CVE-2017-12934 1 Php 1 Php 2025-04-20 5.0 MEDIUM 7.5 HIGH
ext/standard/var_unserializer.re in PHP 7.0.x before 7.0.21 and 7.1.x before 7.1.7 is prone to a heap use after free while unserializing untrusted data, related to the zval_get_type function in Zend/zend_types.h. Exploitation of this issue can have an unspecified impact on the integrity of PHP.
CVE-2016-7479 1 Php 1 Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
In all versions of PHP 7, during the unserialization process, resizing the 'properties' hash table of a serialized object may lead to use-after-free. A remote attacker may exploit this bug to gain arbitrary code execution.
CVE-2017-6441 1 Php 1 Php 2025-04-20 5.0 MEDIUM 7.5 HIGH
The _zval_get_long_func_ex in Zend/zend_operators.c in PHP 7.1.2 allows attackers to cause a denial of service (NULL pointer dereference and application crash) via crafted use of "declare(ticks=" in a PHP script. NOTE: the vendor disputes the classification of this as a vulnerability, stating "Please do not request CVEs for ordinary bugs. CVEs are relevant for security issues only.
CVE-2017-11628 1 Php 1 Php 2025-04-20 6.8 MEDIUM 7.8 HIGH
In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x before 7.1.7, a stack-based buffer overflow in the zend_ini_do_op() function in Zend/zend_ini_parser.c could cause a denial of service or potentially allow executing code. NOTE: this is only relevant for PHP applications that accept untrusted input (instead of the system's php.ini file) for the parse_ini_string or parse_ini_file function, e.g., a web application for syntax validation of php.ini directives.
CVE-2017-5340 2 Netapp, Php 2 Clustered Data Ontap, Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
Zend/zend_hash.c in PHP before 7.0.15 and 7.1.x before 7.1.1 mishandles certain cases that require large array allocations, which allows remote attackers to execute arbitrary code or cause a denial of service (integer overflow, uninitialized memory access, and use of arbitrary destructor function pointers) via crafted serialized data.
CVE-2014-3515 2 Debian, Php 2 Debian Linux, Php 2025-04-12 7.5 HIGH N/A
The SPL component in PHP before 5.4.30 and 5.5.x before 5.5.14 incorrectly anticipates that certain data structures will have the array data type after unserialization, which allows remote attackers to execute arbitrary code via a crafted string that triggers use of a Hashtable destructor, related to "type confusion" issues in (1) ArrayObject and (2) SPLObjectStorage.
CVE-2015-5589 1 Php 1 Php 2025-04-12 10.0 HIGH 9.8 CRITICAL
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.
CVE-2015-8865 2 Apple, Php 2 Mac Os X, Php 2025-04-12 7.5 HIGH 7.3 HIGH
The file_check_mem function in funcs.c in file before 5.23, as used in the Fileinfo component in PHP before 5.5.34, 5.6.x before 5.6.20, and 7.x before 7.0.5, mishandles continuation-level jumps, which allows context-dependent attackers to cause a denial of service (buffer overflow and application crash) or possibly execute arbitrary code via a crafted magic file.
CVE-2016-3171 3 Debian, Drupal, Php 3 Debian Linux, Drupal, Php 2025-04-12 6.8 MEDIUM 8.1 HIGH
Drupal 6.x before 6.38, when used with PHP before 5.4.45, 5.5.x before 5.5.29, or 5.6.x before 5.6.13, might allow remote attackers to execute arbitrary code via vectors related to session data truncation.
