Debian DLA-3376-1 : svgpp - LTS security update

high Nessus Plugin ID 173788

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

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

- 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.
(CVE-2019-6245)

- An issue was discovered in Anti-Grain Geometry (AGG) 2.4 as used in SVG++ (aka svgpp) 1.2.3. A heap-based buffer overflow bug in svgpp_agg_render may lead to code execution. In the render_scanlines_aa_solid function, the blend_hline function is called repeatedly multiple times. blend_hline is equivalent to a loop containing write operations. Each call writes a piece of heap data, and multiple calls overwrite the data in the heap. (CVE-2019-6247)

- 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. (CVE-2021-44960)

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

Solution

Upgrade the svgpp packages.

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