Hi all,

Two Denial-of-Service vulnerabilities were found in the axTLS library (http://axtls.sourceforge.net/). Both 
vulnerabilities were addressed to the project maintainer in a responsible disclosure.
Because the initial deadline was prolonged a few times to fix the issues, but we didn't received any feedback since 
June, the vulnerability details are published now:

Affected versions: axTLS <= 2.1.5
