Bug ID: 21648 Summary: SEGV on unknown address in display_debug_frames 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: 2f3028374138e0990bb8725e14c19138.93474bf24dbdf59dd66beb8d6d58fd36.min Output: 2f3028374138e0990bb8725e14c19138.93474bf24dbdf59dd66beb8d6d58fd36.txt Error in "display_debug_frames": SEGV on unknown address 0x6350000004c0 (pc 0x000000535d71 bp 0x7fffffffdf90 sp 0x7fffffffdc60 T0) in display_debug_frames at binutils/dwarf.c:7494 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/binutils/dwarf.c#L7494) in dump_dwarf_section at binutils/objdump.c:2631 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/binutils/objdump.c#L2631) in bfd_map_over_sections at bfd/section.c:1395 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/section.c#L1395) in dump_dwarf at binutils/objdump.c:2697 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/binutils/objdump.c#L2697) in dump_bfd at binutils/objdump.c:3576 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/binutils/objdump.c#L3576) 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
