MitreCVELIST:CVE-2007-3998CVE-2007-3998
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.
