CVE-2006-7205 php array_fill memory consumption
Last modified: 2007-05-29 06:03:54 EDT
Description of problem:
The array_fill function in ext/standard/array.c in PHP 4.4.2 and 5.1.2 allows
context-dependent attackers to cause a denial of service (memory consumption)
via a large num value.
The memory_limit configuration option is used to constrain the amount of memory
which a script can consume during execution. If this setting is disabled (or
set unreasonably high), it is expected behaviour that scripts will be able to
consume large amounts of memory during script execution.
The memory_limit setting is enabled by default in all versions of PHP
distributed in Red Hat Enterprise Linux.
