Description Joe Orton 2007-06-01 12:35:51 UTC 
Description of problem:
PHP 5.2.3 release: http://www.php.net/releases/5_2_3.php

Fixed an integer overflow inside chunk_split() (by Gerhard Wagner, CVE-2007-2872)
Comment 1 Mark J. Cox 2007-06-01 14:10:52 UTC 
impact=moderate based on analysis of the vulnerability.  Note that to exploit
this the attacker would need to be able to supply an arbitrary argument as a 3rd
argument to chunk_split.  Most scripts that use chunk_script do not specify a
3rd argument or use a fixed argument.
Comment 2 Mark J. Cox 2007-09-03 15:15:17 UTC 
note a more complete fix was included with PHP 5.2.4 release
