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.");
