Description Vladimir Vasilev 2026-09-24 18:19:31 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

NanoSVG 239e102ec contains an incorrect numeric conversion vulnerability in nsvg__curveDivs() during SVG stroke rasterization. A specially crafted SVG document containing an extremely large stroke-width can cause floating-point rounding to produce a zero subdivision angle. The subsequent arc division yields infinity, which is converted to int without range validation, resulting in undefined behavior and process termination, leading to denial of service.

Comment 1 Tom "spot" Callaway 2026-09-25 21:19:45 UTC
This is a false positive, prusa-slicer in Fedora depends on the split out nanosvg package. I've corrected the bundling provides in rawhide so that this doesn't happen again.
