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.
