This isn't anything worth rushing to patch.

The LZ4 file format protected against this issue due to the block size limitations, but that doesn't apply to the LZO algorithm it was based on. The ffmpeg/libav projects use file formats without a limitation preventing exploitation, it's a real vulnerability with working proof of concept exploits.
