> DESCRIPTION:
> Leon Juranic has discovered a vulnerability in PHP, which potentially
> can be exploited by malicious people to compromise a vulnerable
> system.
> 
> The vulnerability is caused due to a boundary error in the PHP
> "wordwrap()" function. This can be exploited to cause a heap-based
> buffer overflow via overly long strings passed to the function.
> 
> The vulnerability has been confirmed in version 5.1.2 and also
> reported in version 4.4.2. Other versions may also be affected.
> 
> SOLUTION:
> Ensure that PHP scripts do not call the "wordwrap()" PHP function
> with input originating from untrusted sources.
