"This update for mupdf to version 1.10a fixes the following issues :

These security issues were fixed :

  - CVE-2016-10132: NULL pointer dereference in regexp
    because of a missing check after allocating memory
    allowing for DoS (bsc#1019877).

  - CVE-2016-10133: Heap buffer overflow write in
    js_stackoverflow allowing for DoS or possible code
    execution (bsc#1019877).

  - CVE-2016-10141: An integer overflow vulnerability
    triggered by a regular expression with nested
    repetition. A successful exploitation of this issue can
    lead to code execution or a denial of service (buffer
    overflow) condition (bsc#1019877).

These non-security issues were fixed :

  - A bug with mutool and saving PDF files using the 'ascii'
    option has been fixed.

  - Stop defining OPJ_STATIC

  - FictionBook (FB2) e-book support.

  - Simple SVG parser (a small subset of SVG only).

  - mutool convert: a new document conversion tool and
    interface.

  - Multi-threaded rendering in mudraw.

  - Updated base 14 fonts from URW.

  - New CJK font with language specific variants.

  - Hyperlink support in EPUB.

  - Alpha channel is now optional in pixmaps.

  - More aggressive purging of cached objects.

  - Partial image decoding for lower memory use when
    banding.

  - Reduced default set of built-in CMap tables to the
    minimum required.

  - FZ_ENABLE_PDF, _XPS, _JS, to disable features at compile
    time.

  - Function level linking.

  - Dropped pdf object generation numbers from public
    interfaces.

  - Simplified PDF page, xobject, and annotation internals.

  - Closing and freeing devices and writers are now separate
    steps.

  - Improved PDF annotation editing interface (still a work
    in progress).

  - Document writer interface.

  - Banded image writer interface.

  - Bidirectional layout for Arabic and Hebrew scripts.

  - Shaping complex scripts for EPUB text layout.

  - Noto fallback fonts for EPUB layout.

  - mutool create :

  - Create new PDF files from scratch.

  - Read an annotated content stream in a text file and
    write a PDF file, automatically embedding font and image
    resources.

  - mutool run :

  + Run JavaScript scripts with MuPDF bindings.

  + The interface is similar to the new Java interface.

  - mutool draw :

  + Optional multi-threaded operation (Windows and
    pthreads).

  + Optional low memory mode (primarily for testing).

  - Set to best anti-alias mode (8) by default. 

  - Ship mupdf-x11-curl as default mupdf. Drop non-curl
    version.

  - New URW fonts with greek and cyrillic.

  - 64-bit file support.

  - Updated FreeType to version 2.6.1.

  - Various font substitution bug fixes.

  - EPUB improvements: User style sheets, GIF images, Table
    of Contents, CJK text, Page margins and many bug fixes."
