In MuPDF 1.12.0, there is an infinite loop vulnerability and application hang in the pdf_parse_array function (pdf/pdf-parse.c) because EOF is not considered. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted pdf file.

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.

This update for mupdf to version 1.12.0 fixes several issues.

These security issues were fixed :

  - CVE-2018-5686: Prevent infinite loop in pdf_parse_array     function because EOF is not considered. Remote attackers     could leverage this vulnerability to cause a denial of     service via a crafted pdf file (bsc#1075936).

  - CVE-2017-15369: The build_filter_chain function in     pdf/pdf-stream.c mishandled a case where a variable may     reside in a register, which allowed remote attackers to     cause a denial of service (Fitz fz_drop_imp     use-after-free and application crash) or possibly have     unspecified other impact via a crafted PDF document     (bsc#1063413).

  - CVE-2017-15587: Prevent integer overflow in     pdf_read_new_xref_section that allowed for DoS     (bsc#1064027).

  - CVE-2017-17866: Fixed mishandling of length changes when     a repair operation occured during a clean operation,     which allowed remote attackers to cause a denial of     service (buffer overflow and application crash) or     possibly have unspecified other impact via a crafted PDF     document (bsc#1074116).

  - CVE-2017-17858: Fixed a heap-based buffer overflow in     the ensure_solid_xref function which allowed a remote     attacker to potentially execute arbitrary code via a     crafted PDF file, because xref subsection object numbers     were unrestricted (bsc#1077161).
