    Package        : tinyxml
    Version        : 2.6.2-4+deb10u1
    CVE ID         : CVE-2021-42260


    An issue has been found in tinyxml, a C++ XML parsing library.
    Crafted XML messages could lead to an infinite loop in
    TiXmlParsingData::Stamp(), which results in a denial of service.


    For Debian 10 buster, this problem has been fixed in version
    2.6.2-4+deb10u1.

    We recommend that you upgrade your tinyxml packages.

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