"This update for libwpd fixes the following issues :

Security issue fixed :

  - CVE-2017-14226: WP1StylesListener.cpp,
    WP5StylesListener.cpp, and WP42StylesListener.cpp in
    libwpd 0.10.1 mishandle iterators, which allows remote
    attackers to cause a denial of service (heap-based
    buffer over-read in the WPXTableList class in
    WPXTable.cpp). This vulnerability can be triggered in
    LibreOffice before 5.3.7. It may lead to suffering a
    remote attack against a LibreOffice application.
    (bnc#1058025)

Bugfixes :

  - Fix various crashes, leaks and hangs when reading
    damaged files found by oss-fuzz.

  - Fix crash when NULL is passed as input stream.

  - Use symbol visibility on Linux. The library only exports
    public functions now.

  - Avoid infinite loop. (libwpd#3)

  - Remove bashism. (libwpd#5)

  - Fix various crashes and hangs when reading broken files
    found with the help of american-fuzzy-lop.

  - Make --help output of all command line tools more
    help2man-friendly.

  - Miscellaneous fixes and cleanups.

  - Generate manpages for the libwpd-tools
