Summary

libvips is a demand-driven, horizontally threaded image processing library. A specially crafted SVG input can cause libvips versions 8.14.3 or earlier to segfault when attempting to parse a malformed UTF-8 character. Users should upgrade to libvips version 8.14.4 (or later) when processing untrusted input.
