CVE-2025-14181
Integer overflow to buffer overflow in soap HTTP parsing
Description
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 then writes into it, producing a heap buffer overflow.
