medium Nessus Plugin ID 126347

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several minor issues have been fixed in mupdf, a lightweight PDF viewer tailored for display of high quality anti-aliased graphics.

CVE-2018-5686

In MuPDF, there was an infinite loop vulnerability and application hang in the pdf_parse_array function (pdf/pdf-parse.c) because EOF not having been considered. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted PDF file.

CVE-2019-6130

MuPDF had a SEGV in the function fz_load_page of the fitz/document.c file, as demonstrated by mutool. This was related to page-number mishandling in cbz/mucbz.c, cbz/muimg.c, and svg/svg-doc.c.

CVE-2018-6192

In MuPDF, the pdf_read_new_xref function in pdf/pdf-xref.c allowed remote attackers to cause a denial of service (segmentation violation and application crash) via a crafted PDF file.

For Debian 8 'Jessie', these problems have been fixed in version 1.5-1+deb8u6.

We recommend that you upgrade your mupdf packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected libmupdf-dev, mupdf, and mupdf-tools packages.
