Package: lrzip
Version: 0.616-1
Usertags: afl
lrzip crashes when decompressing the attached (slightly corrupted) file:
$ lrzcat crash.lrz > /dev/null
Decompressing...
Segmentation fault
This bug was found using American fuzzy lop:
https://packages.debian.org/experimental/afl
Disclaimer: I don't have spare CPU cycles, so I fuzzed only till the
first crash (which took only a few seconds). It's likely that extensive
fuzzing would uncover more interesting crashers. I'd encourage lrzip
maintainers to perform fuzzing with AFL on their own. :-)
