Description Doran Moppert 2017-03-30 03:41:50 UTC 
xmlsec is vulnerable to XML External Entity Expansion via libxml2 (see CVE-2016-9318). A workaround is in progress on the upstream bug report.

Upstream bug:

https://github.com/lsh123/xmlsec/issues/43
Comment 2 Simo Sorce 2017-03-30 13:08:35 UTC 
Is this affecting only the command line utility ?

> Is this affecting only the command line utility ?

The library is affected as well, as it uses libxml2 in the same way.
Comment 4 Simo Sorce 2017-03-31 17:12:01 UTC 
I see no patch for the library upstream.
What's the recommendation ?

The merge request on the upstream ticket applies to the library as well (xmlSecInit() in src/xmlsec.c).
