Debian LTS: DLA-2289-1 Moderate: Mupdf Denial of Service Issues

Several issues have been found in mupdf, a lightweight PDF viewer.

The issues could be exploited by crafted PDF files that result in denial
of service by heap-based buffer overflows, segmentation faults or out of
bound reads.


For Debian 9 stretch, these problems have been fixed in version
1.9a+ds1-4+deb9u5.

We recommend that you upgrade your mupdf packages.

For the detailed security status of mupdf please refer to
its security tracker page at:
