CVE-2019-6245 (GCVE-0-2019-6245)

Vulnerability from cvelistv5 – Published: 2019-01-13 00:00 – Updated: 2024-08-04 20:16

Summary

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.

Severity

No CVSS data available.
