CVE-2018-19882

In Artifex MuPDF 1.14.0, the svg_run_image function in svg/svg-run.c allows remote attackers to cause a denial of service (href_att NULL pointer dereference and application crash) via a crafted svg file, as demonstrated by mupdf-gl.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
