    CVE ID         : CVE-2018-1311
    Debian Bug     : 947431
    
    It was discovered that xerces-c, a validating XML parser library for
    C++, did not correctly scan DTDs. The use-after-free vulnerability
    resulting from this issue would allow a remote attacker to leverage a
    specially crafted XML file in order to crash the application or
    potentially execute arbitrary code.
    Please note that the patch fixing this issue comes at the expense of a
    newly introduced memory leak.
    
    For the stable distribution (buster), this problem has been fixed in
    version 3.2.2+debian-1+deb10u1.
    
    We recommend that you upgrade your xerces-c packages.
    
    For the detailed security status of xerces-c please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/xerces-c
