getID3 through 1.9.26 contains an XML external entity injection vulnerability in the XML2array helper function that fails to properly disable entity loading on PHP before 8.0. Attackers can craft malicious XML metadata in media files to disclose local files, perform server-side request forgery, or cause denial of service through entity expansion.

Missing error checking could result in SQL injection and missing error handling could lead to crashes due to null pointer dereferences.

This is related to https://www.postgresql.org/support/security/CVE-2025-1094/ that was reported to postgres. The reporter used php to showcase the problem.

While working on addressing the report, it was realised that PHP uses the escape functions in a way that does not allow for errors to be reported. Specifically the error parameters is not passed to PQescapeStringConn(), which therefore cannot report an error.

While postgres now tries to make sure that the escaped string will trigger errors on the server-side if the string is invalidly encoded, that still can be insufficient, depending on how the escaped values are used.

It was also noted that several calls to PQescapeIdentifier() do not check for the returned value being NULL, despite that being the documented way that PQescapeIdentifier() (and PQescapeLiteral()) to report errors. Seems like that could cause crashes or at least UB in some of the callsites.

The cdfcountchain function in cdf.c 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 sector-count data, which allows remote attackers to cause a denial of service (application crash) via a crafted CDF file.

Invalid pointer dereference flaws were found in the way file, utility for determining of file types processed header section for certain Composite Document Format (CDF) files. A remote attacker could provide a specially-crafted CDF file, which once inspected by the file utility of the victim would lead to file executable crash.

Buffer overflow in the mconvert function in softmagic.c 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, allows remote attackers to cause a denial of service (application crash) via a crafted Pascal string in a FILEPSTRING conversion.

Fixed bug (Crash while parsing blob data in firebirdfetchblob). (CVE-2021-21704)

The sqlite3VXPrintf function in printf.c in SQLite before 3.8.9 does not properly handle precision and width values during floating-point conversions, which allows context-dependent attackers to cause a denial of service (integer overflow and stack-based buffer overflow) or possibly have unspecified other impact via large integers in a crafted printf function call in a SELECT statement.

In PHP versions 8.3. before 8.3.19 and 8.4. before 8.4.5, a code sequence involving set handler or ??= operator and exceptions can lead to a use-after-free vulnerability. If the third party can control the memory layout leading to this, for example by supplying specially crafted inputs to the script, it could lead to remote code execution.

Fixed bug (Unserialize use-after-free when resizing object's properties hash table). (CVE-2016-7479)

Fixed bug (wddxdeserialize() heap out-of-bound read via phpparsedate()). (CVE-2017-11145)

A stack buffer overflow exists in the latest stable release of PHP-7.1.5 and PHP-5.6.30 in PHP INI parsing API, which may accept network / local filesystem input. On malformed inputs, a stack buffer overflow in zendinidoop() could write 1-byte off a fixed size stack buffer. On installations with the stack smashing mitigation, this would cause an immediate DoS; upto optimization levels, build options and stack buffer overflow mitigations, this vulnerability may allow corrupting other local variables or the frame pointer, potentially allows remotely executing code.

Fixed bug (wddx parsing empty boolean tag leads to SIGSEGV). (CVE-2017-11143)

The SplObjectStorage unserialize implementation in ext/spl/splobserver.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.

Zend/zendexceptions.c in PHP, possibly 5.x before 5.6.28 and 7.x before 7.0.13, allows remote attackers to cause a denial of service (infinite loop) via a crafted Exception object in serialized data, a related issue to CVE-2015-8876.

Fixed bug (integer overflow in ZipArchive::getFrom). (CVE-2016-3078)

Integer overflow in the 16 bit variable reference counter in PHP 4 allows context-dependent attackers to execute arbitrary code by overflowing this counter, which causes the same variable to be destroyed twice, a related issue to CVE-2007-1286.

DISPUTED The Zend Engine in PHP before 5.4.16 RC1, and 5.5.0 before RC2, does not properly determine whether a parser error occurred, which allows context-dependent attackers to cause a denial of service (memory consumption and application crash) via a crafted function definition, as demonstrated by an attack within a shared web-hosting environment. NOTE: the vendor's http://php.net/security-note.php page says "for critical security situations you should be using OS-level security by running multiple web servers each as their own user id."

An issue was discovered in PHP 7.3.x before 7.3.1. An invalid multibyte string supplied as an argument to the mbsplit() function in ext/mbstring/phpmbregex.c can cause PHP to execute memcpy() with a negative argument, which could read and write past buffers allocated for the data.
