Description Pedro Sampaio 2017-12-26 21:26:04 UTC

pdf/pdf-write.c in Artifex MuPDF before 1.12.0 mishandles certain length changes when a repair operation occurs during a clean operation, which allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted PDF document.
