Package        : expat
CVE ID         : CVE-2019-15903
Debian Bug     : 939394

It was discovered that Expat, an XML parsing C library, did not properly
handled internal entities closing the doctype, potentially resulting in
denial of service or information disclosure if a malformed XML file is
processed.

For the oldstable distribution (stretch), this problem has been fixed
in version 2.2.0-2+deb9u3.

For the stable distribution (buster), this problem has been fixed in
version 2.2.6-2+deb10u1.

We recommend that you upgrade your expat packages.
