Update libebml to 1.3.7

Authored by kyrios123 on Mar 15 2019, 6:01 PM.


  • Fixed the handling of Unicode codepoints > U+FFFF.
  • Fixed building with gcc >= 7.
  • Converted the build system from autoconf/automake to cmake.
  • Fixed undefined behavior when reading signed integers with negative values from files (though compilers implemented this the way we wanted them to already).
  • Fixed a small memory leak when reading an element runs into an I/O exception (e.g. due to having reached the end of the file).
  • Fixed the EbmlMaster::GetDataStart() function returning wrong values for elements with an infinite/unknown size.
  • Fixed finding the next element ID when garbage data is encountered during the scan for the ID.
  • Fixed several potential situations where reading child element data could exceed the parent element's size.
