Hi,

I did a quick run with american fuzzy lop on libabw and it found the
attached crasher.
Attached both sample exposing segfault and asan/valgrind output. It's
an invalid memory read access.

This has already been found by coverity, but thanks anyway.


As here are a lot of people working on import filters: These are very
suspectible to these type of memory access errors and they can often
easily be found with fuzzing. You may wanna have a look at
https://fuzzing-project.org

I know... I used zzuf on some of our libs in the past. And I have been
using afl since I discovered it 4-5 weeks ago. I have already fixed over
20 crashes/hangs in various libraries, but I still have got more to go
through.
