- Details

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 arraymerge() when the total element count of packed arrays exceeds 32-bit limits or HTMAXSIZE, due to an integer overflow in the precomputation of element counts using zendhashnumelements(). This may lead to memory corruption or crashes and affect the integrity and availability of the target server.
