An issue was discovered in Anti-Grain Geometry (AGG) 2.4 as used in SVG++ (aka svgpp) 1.2.3. In the function agg::cell_aa::not_equal, dx is assigned to (x2 - x1). If dx >= dx_limit, which is (16384 << poly_subpixel_shift), this function will call itself recursively. There can be a situation where (x2 - x1) is always bigger than dx_limit during the recursion, leading to continual stack consumption.

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

    (CVE-2019-6245)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3376 advisory.

    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.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Debian 9 host has a package installed that is affected by a vulnerability as referenced in the dla-2872 advisory.

    Stack overflow due to infinite recursion was fixed in agg, the Anti-Grain Geometry graphical toolkit. For     Debian 9 stretch, this problem has been fixed in version 2.5+dfsg1-11+deb9u1. We recommend that you     upgrade your agg packages.

A stack overflow vulnerability was discovered in AGG, the AntiGrain Geometry graphical toolkit, that may lead to code execution if a malformed file is processed. Since AGG only provides a static library, the desmume and exactimage packages were rebuilt against the latest security update.

For Debian 8 'Jessie', this problem has been fixed in version 2.5+dfsg1-9+deb8u1.

We recommend that you upgrade your agg packages.
