Bug ID: 21641 Summary: SEGV on unknown address in setup_sections Product: binutils Version: 2.29 (HEAD) Status: UNCONFIRMED Severity: critical Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: aadamski at quarkslab dot com Target Milestone: --- Hello there, I have been fuzzing objdump with American Fuzzy Lop + ASAN/UBSAN. Please find attached the minimized file causing the issue ("Input") and the ASAN report log ("Output"). Below is the reduced stacktrace with links to the corresponding source lines on a GitHub mirror. The configuration settings used were `--enable-targets=all --disable-shared`. The compilation flags used were `-g -O2 -fno-omit-frame-pointer -fsanitize=address -fno-sanitize-recover=all`. The command used was `objdump -afpxDSsgetTrR <file>`. Let me know if there is any additional information I can provide. -- Input: ad5b18e3ab2e99645d454bd218e7e425.4a145a99483654b79949d806705c075c.min Output: ad5b18e3ab2e99645d454bd218e7e425.4a145a99483654b79949d806705c075c.txt Error in "setup_sections": SEGV on unknown address 0x611002960648 (pc 0x7ffff6f72c3a bp 0x7fffffffdc90 sp 0x7fffffffd418 T0) in setup_sections at bfd/som.c:2125 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/som.c#L2125) in som_object_p at bfd/som.c:2511 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/som.c#L2511) in bfd_check_format_matches at bfd/format.c:311 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/format.c#L311) in display_object_bfd at binutils/objdump.c:3608 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/binutils/objdump.c#L3608) in display_any_bfd at binutils/objdump.c:3699 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/binutils/objdump.c#L3699) in display_file at binutils/objdump.c:3720 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/binutils/objdump.c#L3720) in main at binutils/objdump.c:4024 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/binutils/objdump.c#L4024) -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
