Package : mupdf
CVE ID : CVE-2016-6265 CVE-2016-6525
Debian Bug : 832031 833417

Two vulnerabilities were discovered in MuPDF, a lightweight PDF viewer.
The Common Vulnerabilities and Exposures project identifies the
following problems:

CVE-2016-6265

Marco Grassi discovered a use-after-free vulnerability in MuPDF. An
attacker can take advantage of this flaw to cause an application
crash (denial-of-service), or potentially to execute arbitrary code
with the privileges of the user running MuPDF, if a specially
crafted PDF file is processed.

CVE-2016-6525

Yu Hong and Zheng Jihong discovered a heap overflow vulnerability
within the pdf_load_mesh_params function, allowing an attacker to
cause an application crash (denial-of-service), or potentially to
execute arbitrary code with the privileges of the user running
MuPDF, if a specially crafted PDF file is processed.

For the stable distribution (jessie), these problems have been fixed in
version 1.5-1+deb8u1.

We recommend that you upgrade your mupdf packages.
