In SVGPP SVG++ library 1.3.0, the XMLDocument::getRoot function in the renderDocument function handled the XMLDocument object improperly, returning a null pointer in advance at the second if, resulting in a null pointer reference behind the renderDocument function.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

    Package        : svgpp     Version        : 1.2.3+dfsg1-6+deb10u1     CVE ID         : CVE-2019-6245 CVE-2019-6247 CVE-2021-44960

    Multiple security issues were discovered in svgpp: a C++ library for parsing and     rendering Scalable Vector Graphics (SVG) files.

    CVE-2021-44960        The XMLDocument::getRoot function in the renderDocument function handled the        XMLDocument object improperly. Specifically, it returned a null pointer        prematurely at the second if statement, resulting in a null pointer        reference behind the renderDocument function.

    CVE-2019-6245 and CVE-2019-6247:
       issues were discovered in Anti-Grain Geometry (AGG) within the function        agg::cell_aa::not_equal. Since svgpp is a header-only library, the issue is        only transitive in theory. As a result, only a dependency version hardening        has been added to the control file.

    For Debian 10 buster, these problems have been fixed in version     1.2.3+dfsg1-6+deb10u1.

    We recommend that you upgrade your svgpp packages.
