CVE-2012-0845

Published: 14 February 2012

SimpleXMLRPCServer.py in SimpleXMLRPCServer in Python before 2.6.8, 2.7.x before 2.7.3, 3.x before 3.1.5, and 3.2.x before 3.2.3 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via an XML-RPC POST request that contains a smaller amount of data than specified by the Content-Length header.

Notes

Author	Note
jdstrand	reproducer doesn't work on 8.04 LTS python2.4, but the code is sufficiently similar that we'll patch
