Debian DLA-2872-1 : agg - LTS security update

high Nessus Plugin ID 156418

Synopsis

The remote Debian host is missing a security-related update.

Description

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

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

Solution

Upgrade the agg packages.

For Debian 9 stretch, this problem has been fixed in version 2.5+dfsg1-11+deb9u1.
