BIT-PHP-MIN-2026-91768 IPv6 ACL bypass in FastCGI listen.allowed_clients due to partial address comparison (memcmp 12 bytes)

The IPv6 branch of the FastCGI client access check compares only the first 12 bytes of a 16-byte IPv6 address, so listen.allowedclients matches on a /96 prefix instead of the exact address. An attacker who can source an address sharing the first 96 bits with an allowed one passes the check and...

BIT-PHP-MIN-2026-91766 Cross-origin credential leak in HTTP stream wrapper redirects

When the http:// stream wrapper follows a redirect it forwards the user-supplied Authorization, Cookie and Proxy-Authorization headers unchanged, even when the redirect target is a different host, a different port, or a downgrade from HTTPS to HTTP. A server that can steer a redirect therefore...

BIT-PHP-2026-92842 OOB read / info leak in convert.* stream filters when line-break-chars contains NUL

The convert.base64-encode, convert.quoted-printable-encode and convert.quoted-printable-decode stream filters accept a line-break-chars option whose length is tracked separately from the string itself. The filter constructors duplicate the value with pestrdup, which stops at the first NUL byte,...

BIT-PHP-2026-91765 SOAP: Unbounded Recursion in Server-Side cleanup_xml_node

cleanupxmlnode in the SOAP XML parser recurses once per XML nesting level with no depth limit. An unauthenticated attacker can post a SOAP request containing tens of thousands of nested elements to any SoapServer endpoint, exhaust the stack and crash the process. The same unbounded recursion exis...

BIT-PHP-MIN-2025-14181 Integer overflow to buffer overflow in soap HTTP parsing

The SOAP HTTP client guards its response buffer growth with a check that relies on signed integer overflow, which is undefined behaviour and is not guaranteed to trigger. When the check is optimised away, a malicious SOAP server can make the client allocate a buffer far smaller than the data it...

SUSE CVE-2024-11236

In PHP versions 8.1. before 8.1.31, 8.2. before 8.2.26, 8.3. before 8.3.14, uncontrolled long string inputs to ldapescape function on 32-bit systems can cause an integer overflow, resulting in an out-of-bounds write...

SUSE CVE-2007-0988

The zendhashinit function in PHP 5 before 5.2.1 and PHP 4 before 4.4.5, when running on a 64-bit platform, allows context-dependent attackers to cause a denial of service infinite loop by unserializing certain integer expressions, which only cause 32-bit arguments to be used after the check for a...
