Description Tomas Hoger 2009-04-07 10:50:19 UTC
PHP 5.2.9 upstream release notes mention following security fix:

  Fixed a segfault when malformed string is passed to json_decode(). (Scott)

  http://www.php.net/releases/5_2_9.php

Upstream patch:
http://cvs.php.net/viewvc.cgi/php-src/ext/json/JSON_parser.c?r1=1.1.2.14&r2=1.1.2.15

JSON extension was only introduced in PHP 5.2.0, earlier versions of php (such as those shipped in Red Hat Enterprise Linux 2.1, 3, 4, and 5) are not affected by this problem.

Comment 2 Tomas Hoger 2009-04-09 07:38:21 UTC
CVE-2009-1271:
The JSON_parser function (ext/json/JSON_parser.c) in PHP 5.2.x before
5.2.9 allows remote attackers to cause a denial of service
(segmentation fault) via a malformed string to the json_decode API
function.
