Debian DSA-4794-1 : mupdf - security update

medium Nessus Plugin ID 143187
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

A heap-based buffer overflow flaw was discovered in MuPDF, a lightweight PDF viewer, which may result in denial of service or the execution of arbitrary code if malformed documents are opened.

Solution

Upgrade the mupdf packages.

For the stable distribution (buster), this problem has been fixed in version 1.14.0+ds1-4+deb10u2.
