[PATCH 1/2] tests: dumpe2fs against an image with bad os_type.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The os_type here is large enough to be negative when interpreted as a
signed integer.

This test case was generated by american fuzzy lop, starting from a
base filesystem image from files.fuzzing-project.org.
