How to fix?

There is no fixed version for RHEL:10 rh-php56-php.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rh-php56-php package and not the rh-php56-php package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

Zend/zend_hash.c in PHP before 7.0.15 and 7.1.x before 7.1.1 mishandles certain cases that require large array allocations, which allows remote attackers to execute arbitrary code or cause a denial of service (integer overflow, uninitialized memory access, and use of arbitrary destructor function pointers) via crafted serialized data.
