CVE-2025-6491 (GCVE-0-2025-6491)

Vulnerability from cvelistv5 – Published: 2025-07-13 22:10 – Updated: 2025-11-04 21:14

Title

NULL Pointer Dereference in PHP SOAP Extension via Large XML Namespace Prefix

Summary

In PHP versions:8.1.* before 8.1.33, 8.2.* before 8.2.29, 8.3.* before 8.3.23, 8.4.* before 8.4.10 when parsing XML data in SOAP extensions, overly large (>2Gb) XML namespace prefix may lead to null pointer dereference. This may lead to crashes and affect the availability of the target server.

Severity ?

5.9 (Medium)

CVE-2025-14178 (GCVE-0-2025-14178)

Vulnerability from cvelistv5 – Published: 2025-12-27 19:27 – Updated: 2026-01-24 11:04

Title

Heap buffer overflow in array_merge()

Summary

In PHP versions:8.1.* before 8.1.34, 8.2.* before 8.2.30, 8.3.* before 8.3.29, 8.4.* before 8.4.16, 8.5.* before 8.5.1, a heap buffer overflow occurs in array_merge() when the total element count of packed arrays exceeds 32-bit limits or HT_MAX_SIZE, due to an integer overflow in the precomputation of element counts using zend_hash_num_elements(). This may lead to memory corruption or crashes and affect the integrity and availability of the target server.

Severity ?

6.5 (Medium)

CVE-2025-1220 (GCVE-0-2025-1220)

Vulnerability from cvelistv5 – Published: 2025-07-13 22:18 – Updated: 2025-11-04 21:09

Title

Null byte termination in hostnames

Summary

In PHP versions:8.1.* before 8.1.33, 8.2.* before 8.2.29, 8.3.* before 8.3.23, 8.4.* before 8.4.10 some functions like fsockopen() lack validation that the hostname supplied does not contain null characters. This may lead to other functions like parse_url() treat the hostname in different way, thus opening way to security problems if the user code implements access checks before access using such functions.

Severity ?

3.7 (Low)

CVE-2025-14177 (GCVE-0-2025-14177)

Vulnerability from cvelistv5 – Published: 2025-12-27 19:33 – Updated: 2025-12-29 16:01

Title

Information Leak of Memory in getimagesize

Summary

In PHP versions:8.1.* before 8.1.34, 8.2.* before 8.2.30, 8.3.* before 8.3.29, 8.4.* before 8.4.16, 8.5.* before 8.5.1, the getimagesize() function may leak uninitialized heap memory into the APPn segments (e.g., APP1) when reading images in multi-chunk mode (such as via php://filter). This occurs due to a bug in php_read_stream_all_chunks() that overwrites the buffer without advancing the pointer, leaving tail bytes uninitialized. This may lead to information disclosure of sensitive heap data and affect the confidentiality of the target server.

Severity ?

6.3 (Medium)

CVE-2025-1735 (GCVE-0-2025-1735)

Vulnerability from cvelistv5 – Published: 2025-07-13 22:27 – Updated: 2025-11-04 21:09

Title

pgsql extension does not check for errors during escaping

Summary

In PHP versions:8.1.* before 8.1.33, 8.2.* before 8.2.29, 8.3.* before 8.3.23, 8.4.* pgsql and pdo_pgsql escaping functions do not check if the underlying quoting functions returned errors. This could cause crashes if Postgres server rejects the string as invalid.

Severity ?

5.9 (Medium)

CVE-2025-14180 (GCVE-0-2025-14180)

Vulnerability from cvelistv5 – Published: 2025-12-27 19:21 – Updated: 2025-12-29 16:00

Title

NULL Pointer Dereference in PDO quoting

Summary

In PHP versions 8.1.* before 8.1.34, 8.2.* before 8.2.30, 8.3.* before 8.3.29, 8.4.* before 8.4.16, 8.5.* before 8.5.1 when using the PDO PostgreSQL driver with PDO::ATTR_EMULATE_PREPARES enabled, an invalid character sequence (such as \x99) in a prepared statement parameter may cause the quoting function PQescapeStringConn to return NULL, leading to a null pointer dereference in pdo_parse_params() function. This may lead to crashes (segmentation fault) and affect the availability of the target server.

Severity ?

8.2 (High)
