Comment 2 Matthias Gerstner 2017-02-06 16:52:41 UTC

QA reproducer:

Using the PoC file from the upstream bug
https://github.com/libimobiledevice/libplist/files/712874/poc17.txt I was able
to reproduce the issue in all codestreams like this:

  plistutil -i poc17.txt

This causes a segmentation fault.
