CVE-2023-40032: Potential segfault due to NULL pointer dereference in libvips
First published: Mon Sep 11 2023(Updated: )
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.
