Title
ThorVG: Null pointer dereference in SVG loader causes crash via 6-byte malformed input
Summary
Thor Vector Graphics (ThorVG) is a production-ready vector graphics engine. Prior to version 1.0.5, a null pointer dereference in SvgLoader::run() allows any caller that passes untrusted SVG data to Picture::load() to crash the process with a 6-byte payload. This issue has been patched in version 1.0.5.
