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.
