Last modified
CVE-2006-4812 is a vulnerability of currently unknown severity. Integer overflow in PHP 5 up to 5.1.6 and 4 before 4.3.0 allows remote attackers to execute arbitrary code via an argument to the unserialize PHP function with a large value for the number of array elements, which triggers the overflow in the Zend Engine ecalloc function (Zend/zend_alloc.c).. EPSS estimates a 15.01% chance of exploitation in the next 30 days.
