CVE-2017-16642 4 Canonical, Debian, Netapp and 1 more 5 Ubuntu Linux, Debian Linux, Clustered Data Ontap and 2 more 2026-05-13 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-2016-10161 1 Php 1 Php 2026-05-13 5.0 MEDIUM 7.5 HIGH
The object_common1 function in ext/standard/var_unserializer.c in PHP before 5.6.30, 7.0.x before 7.0.15, and 7.1.x before 7.1.1 allows remote attackers to cause a denial of service (buffer over-read and application crash) via crafted serialized data that is mishandled in a finish_nested_data call.
CVE-2017-9226 2 Oniguruma Project, Php 2 Oniguruma, Php 2026-05-13 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 heap out-of-bounds write or read occurs in next_state_val() during regular expression compilation. Octal numbers larger than 0xff are not handled correctly in fetch_token() and fetch_token_in_cc(). A malformed regular expression containing an octal number in the form of '\700' would produce an invalid code point value larger than 0xff in next_state_val(), resulting in an out-of-bounds write memory corruption.
CVE-2017-12934 1 Php 1 Php 2026-05-13 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-2017-9228 2 Oniguruma Project, Php 2 Oniguruma, Php 2026-05-13 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 heap out-of-bounds write occurs in bitset_set_range() during regular expression compilation due to an uninitialized variable from an incorrect state transition. An incorrect state transition in parse_char_class() could create an execution path that leaves a critical local variable uninitialized until it's used as an index, resulting in an out-of-bounds write memory corruption.
CVE-2017-7272 1 Php 1 Php 2026-05-13 5.8 MEDIUM 7.4 HIGH
PHP through 7.1.11 enables potential SSRF in applications that accept an fsockopen or pfsockopen hostname argument with an expectation that the port number is constrained. Because a :port syntax is recognized, fsockopen will use the port number that is specified in the hostname argument, instead of the port number in the second argument of the function.
CVE-2017-7890 1 Php 1 Php 2026-05-13 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-2016-10162 1 Php 1 Php 2026-05-13 5.0 MEDIUM 7.5 HIGH
The php_wddx_pop_element function in ext/wddx/wddx.c in PHP 7.0.x before 7.0.15 and 7.1.x before 7.1.1 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an inapplicable class name in a wddxPacket XML document, leading to mishandling in a wddx_deserialize call.
CVE-2016-5873 1 Php 1 Pecl Http 2026-05-13 7.5 HIGH 9.8 CRITICAL
Buffer overflow in the HTTP URL parsing functions in pecl_http before 3.0.1 might allow remote attackers to execute arbitrary code via non-printable characters in a URL.
CVE-2017-11144 1 Php 1 Php 2026-05-13 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, the openssl extension PEM sealing code did not check the return value of the OpenSSL sealing function, which could lead to a crash of the PHP interpreter, related to an interpretation conflict for a negative number in ext/openssl/openssl.c, and an OpenSSL documentation omission.
CVE-2017-11362 1 Php 1 Php 2026-05-13 7.5 HIGH 9.8 CRITICAL
In PHP 7.x before 7.0.21 and 7.1.x before 7.1.7, ext/intl/msgformat/msgformat_parse.c does not restrict the locale length, which allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) or possibly have unspecified other impact within International Components for Unicode (ICU) for C/C++ via a long first argument to the msgfmt_parse_message function.
CVE-2017-11143 1 Php 1 Php 2026-05-13 5.0 MEDIUM 7.5 HIGH
In PHP before 5.6.31, an invalid free in the WDDX deserialization of boolean parameters could be used by attackers able to inject XML for deserialization to crash the PHP interpreter, related to an invalid free for an empty boolean element in ext/wddx/wddx.c.
CVE-2017-11147 2 Netapp, Php 2 Clustered Data Ontap, Php 2026-05-13 6.4 MEDIUM 9.1 CRITICAL
In PHP before 5.6.30 and 7.x before 7.0.15, the PHAR archive handler could be used by attackers supplying malicious archive files to crash the PHP interpreter or potentially disclose information due to a buffer over-read in the phar_parse_pharfile function in ext/phar/phar.c.
CVE-2016-10160 3 Debian, Netapp, Php 3 Debian Linux, Clustered Data Ontap, Php 2026-05-13 7.5 HIGH 9.8 CRITICAL
Off-by-one error in the phar_parse_pharfile function in ext/phar/phar.c in PHP before 5.6.30 and 7.0.x before 7.0.15 allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a crafted PHAR archive with an alias mismatch.
CVE-2017-9067 2 Modx, Php 2 Modx Revolution, Php 2026-05-13 4.4 MEDIUM 7.0 HIGH
In MODX Revolution before 2.5.7, when PHP 5.3.3 is used, an attacker is able to include and execute arbitrary files on the web server due to insufficient validation of the action parameter to setup/index.php, aka directory traversal.
CVE-2017-7963 1 Php 1 Php 2026-05-13 5.0 MEDIUM 7.5 HIGH
The GNU Multiple Precision Arithmetic Library (GMP) interfaces for PHP through 7.1.4 allow attackers to cause a denial of service (memory consumption and application crash) via operations on long strings. NOTE: the vendor disputes this, stating "There is no security issue here, because GMP safely aborts in case of an OOM condition. The only attack vector here is denial of service. However, if you allow attacker-controlled, unbounded allocations you have a DoS vector regardless of GMP's OOM behavior.
CVE-2017-12868 2 Php, Simplesamlphp 2 Php, Simplesamlphp 2026-05-13 7.5 HIGH 9.8 CRITICAL
The secureCompare method in lib/SimpleSAML/Utils/Crypto.php in SimpleSAMLphp 1.14.13 and earlier, when used with PHP before 5.6, allows attackers to conduct session fixation attacks or possibly bypass authentication by leveraging missing character conversions before an XOR operation.
CVE-2025-14179 1 Php 1 Php 2026-05-12 N/A 9.8 CRITICAL
In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, the PDO Firebird driver improperly handles NUL bytes when preparing SQL queries. During token-by-token query construction, a string token containing a NUL byte is copied via strncat(), which stops at the NUL byte, dropping the closing quote and causing subsequent SQL tokens to be interpreted as part of the string. This allows SQL injection when attacker-controlled values are quoted via PDO::quote() and embedded in SQL statements.
CVE-2026-6722 1 Php 1 Php 2026-05-12 N/A 9.8 CRITICAL
In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, the SOAP extension's object deduplication mechanism stores pointers to PHP objects in a global map without incrementing their reference counts. When an apache:Map node contains duplicate keys, processing the second entry overwrites the first in the temporary result map, freeing the original PHP object while its stale pointer remains in the map. A subsequent href reference to the freed node can copy the dangling pointer into the result. As PHP string allocations can reclaim the freed memory region, an attacker with control over the SOAP request body can exploit this use-after-free to achieve remote code execution.
CVE-2026-6735 1 Php 1 Php 2026-05-12 N/A 6.1 MEDIUM
In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, 8.5.* before 8.5.6, due to improper sanitation of user data, it allows an attacker to compose an URL, which will cause the target to execute arbitrary JavaScript code (XSS) on the target's machine when the target is viewing the PHP-FPM status page.
