It was discovered that Expat, an XML parsing C library, did not properly handled XML input including XML names that contain a large number of colons, potentially resulting in denial of service.

For the stable distribution (stretch), this problem has been fixed in version 2.2.0-2+deb9u2.

We recommend that you upgrade your expat packages.

For the detailed security status of expat please refer to its security tracker page at: https://security-tracker.debian.org/tracker/expat
