Description:
 The wordwrap function in PHP 4 before 4.4.8, and PHP 5 before 5.2.4, does
 not properly use the breakcharlen variable, which allows remote attackers
 to cause a denial of service (divide-by-zero error and application crash,
 or infinite loop) via certain arguments, as demonstrated by a 'chr(0), 0,
 ""' argument set.
