An attacker can craft a PDF document which, when opened in the victim host, might consume vast amounts of memory, crash the program, or, in some cases, execute code in the context in which the application is running.

For the oldstable distribution (jessie), these problems have been fixed in version 1.5-1+deb8u4.

For the stable distribution (stretch), these problems have been fixed in version 1.9a+ds1-4+deb9u3.

We recommend that you upgrade your mupdf packages.

For the detailed security status of mupdf please refer to its security tracker page at: [link moved to references]");
