"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).

For non-security changes please refer to the changelog."
