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