FKIE_CVE-2007-3998
Vulnerability from fkie_nvd - Published: 2007-09-04 18:17 - Updated: 2026-06-16 22:43
Severity
Summary
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.
