Description Murray McAllister 2014-03-19 05:27:38 UTC 
A flaw was found in the way Python's zipfile module processed malformed ZIP files. Processing a malicious ZIP file could lead to 100% CPU usage. This would be an issue if you are running a web service that accepts and processes ZIP files from untrusted sources.

At least Python 3 is affected. It is not yet known if older versions (such as version 2.7) are affected.
