Describe CVE-2007-1885.
What is CVE-2007-1885?
Integer overflow in the str_replace function in PHP 4 before 4.4.5 and PHP 5 before 5.2.1 allows context-dependent attackers to execute arbitrary code via a single character search string in conjunction with a long replacement string, which overflows a 32 bit length counter.  NOTE: this is probably the same issue as CVE-2007-0906.6..
