Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the mupdf packages.

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