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).

Two security issues were discovered in mupdf, a lightweight PDF viewer.

CVE-2017-14687 MuPDF allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .xps file. This occurs because of mishandling of XML tag name comparisons.

CVE-2017-15587 An integer overflow was discovered in pdf_read_new_xref_section in pdf/pdf-xref.c

For Debian 7 'Wheezy', these problems have been fixed in version 0.9-2+deb7u4.

We recommend that you upgrade your mupdf packages.

Multiple vulnerabilities have been found in MuPDF, a PDF file viewer, which may result in denial of service or the execution of arbitrary code.

  - CVE-2017-14685, CVE-2017-14686, and CVE-2017-14687     WangLin discovered that a crafted .xps file can crash     MuPDF and potentially execute arbitrary code in several     ways, since the application makes unchecked assumptions     on the entry format.

  - CVE-2017-15587     Terry Chia and Jeremy Heng discovered an integer     overflow that can cause arbitrary code execution via a     crafted .pdf file.

The remote host is affected by the vulnerability described in GLSA-201811-15 (MuPDF: Multiple vulnerabilities)
