Rhodri James discovered a heap use-after-free vulnerability in the doContent function in Expat, an XML parsing C library, which could result in denial of service or potentially the execution of arbitrary code, if a malformed XML file is processed.

For Debian 8 jessie, these problems have been fixed in version 2.1.0-6+deb8u9.

For Debian 9 stretch, these problems have been fixed in version 2.2.0-2+deb9u6.

We recommend that you upgrade your expat packages.
