   An update that fixes one vulnerability is now available.

Description:

   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
