Integer overflow in the wordwrap function in string.c in PHP 4.4.2 and 5.1.2 might allow context-dependent attackers to execute arbitrary code via certain long arguments that cause a small buffer to be allocated, which triggers a heap-based buffer overflow in a memcpy function call, a different vulnerability than CVE-2002-1396.

Heap-based buffer overflow in the wordwrap function in PHP after 4.1.2 and before 4.3.0 may allow attackers to cause a denial of service or execute arbitrary code.
