Description Mark J. Cox 2006-06-22 08:36:25 UTC

CVE-2006-2657: A bug in zend_hash_del() allowed attackers to prevent
unsetting of some variables.  Fixed upstream in PHP 5.1.4

This could be bad for scripts where register_globals is on as often variables
are only initialized by unsetting them,  but it could also have side effects on
other scripts depending on the script.

Upstream fix:

http://cvs.php.net/viewcvs.cgi/Zend/zend_hash.c?hideattic=0&r1=1.87.4.8.2.1&r2=1.87.4.8.2.2

Affects RHEL3, RHEL4 (RHEL2.1 separate tracking bug)
