CVE-2007-3998  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade RHEL:10 php to version 0:5.1.6-3.el4s1.8 or higher.
This issue was patched in RHSA-2007:0891.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php package and not the php package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
