Package        : expat
CVE ID         : CVE-2018-20843
Debian Bug     : 931031

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.
