Bug ID: 20907
Summary: Internal error in peicode.h causes program to abort
Product: binutils
Version: 2.28 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org

Target Milestone: ---
Dear all,
Using AFLFast (https://github.com/mboehme/aflfast), a fork of AFL, we found an
input causing different programs (addr2line, strings and size) to abort due to
an exception in peicode.h.
The bug was found on Ubuntu 14.04 64-bit & binutils was checked out from
https://github.com/bminor/binutils-gdb repository. Its commit is
268ebe95201d2ebdcf68cad9dc67ff6d1e25be9e (Fri Nov 18 14:15:12 2016). We also
checked and confirmed the bug using the newest development version of binutils
& binutils 2.24.
To reproduce:
printf
"\x00\x00\xff\xff\x00\x00\x4c\x01\x30\x30\x30\x30\x24\x00\x00\x00\x00\x00\x01\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x00\x00\x30\x30\x30\x30\x30\x30\x30\x30"
> fd
addr2line -e fd
OR
size fd
OR
strings -d fd
Error message:
BFD (GNU Binutils) 2.27.51.20161128 internal error, aborting at
../../bfd/peicode.h:896 in pe_ILF_build_a_bfd
Best regards,
Thuan
