Summary

Stack-based buffer overflow in the date_from_ISO8601 function in ext/xmlrpc/libxmlrpc/xmlrpc.c in PHP before 5.2.7 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code by including a timezone field in a date, leading to improper XML-RPC encoding.
