Package : mupdf Version : 1.5-1+deb8u6 CVE ID : CVE-2018-5686 CVE-2019-6130 CVE-2018-6192 Debian Bug : 887130 888487 918971
Several minor issues have been fixed in mupdf, a lightweight PDF viewer tailored for display of high quality anti-aliased graphics.
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.
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.
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.
