Comment # 5 on bug 1194245 from Alexander Bergmann

Hi Petr,

I've checked again and found the following commit inside the mdbtools repo that
references the oss-fuzz id 35972:

commit 03391fc913d41a55b16f0204e5533db39549ab33
Author: Hans de Goede <hdegoede@redhat.com>

    Always check mdb_read_table() return value

    A couple of places were missing NULL return value checks for
    mdb_read_table()'s return value. Add these.

    This fixes a NULL pointer deref while running ./test_script.sh
    on the test mdb file from oss-fuzz/35972 .

    Note this does NOT fix the original problem reported in oss-fuzz/35972
    which reports a "Dynamic-stack-buffer-overflow WRITE 16" issue,
    which I've been unable to reproduce.


However, comment 0 was talking about a "stack-based buffer overflow" and this
commit about a "NULL pointer deref". So it's kind of a mess.
