Detailsinfo

A vulnerability was found in Anti-Grain Geometry 2.4. It has been rated as problematic. Affected by this issue is the function agg::cell_aa::not_equal. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is availability. CVE summarizes:

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 bug was discovered 01/12/2019. The weakness was published 01/13/2019 (Website). The advisory is shared for download at github.com. This vulnerability is handled as CVE-2019-6245 since 01/12/2019.
