Bug ID: 21651 Summary: heap-buffer-overflow in add_symbol Product: binutils Version: 2.29 (HEAD) Status: UNCONFIRMED Severity: normal 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: 282cc553a70cccddc4535d4bb3db5692.6a1a70e215d3fd538023ab8e5737b3c8.min Output: 282cc553a70cccddc4535d4bb3db5692.6a1a70e215d3fd538023ab8e5737b3c8.txt Error in "add_symbol": heap-buffer-overflow in add_symbol at bfd/vms-alpha.c:1125 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/vms-alpha.c#L1125) in _bfd_vms_slurp_egsd at bfd/vms-alpha.c:1307 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/vms-alpha.c#L1307) in _bfd_vms_slurp_object_records at bfd/vms-alpha.c:2456 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/vms-alpha.c#L2456) in alpha_vms_object_p at bfd/vms-alpha.c:2640 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/vms-alpha.c#L2640) 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) Input: 5deafefa1ca077a686a06b18e93f6e2e.484ddbe005142cc897588a715f2572f7.min Output: 5deafefa1ca077a686a06b18e93f6e2e.484ddbe005142cc897588a715f2572f7.txt Error in "add_symbol": heap-buffer-overflow in add_symbol at bfd/vms-alpha.c:1120 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/vms-alpha.c#L1120) in _bfd_vms_slurp_egsd at bfd/vms-alpha.c:1265 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/vms-alpha.c#L1265) in _bfd_vms_slurp_object_records at bfd/vms-alpha.c:2456 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/vms-alpha.c#L2456) in alpha_vms_object_p at bfd/vms-alpha.c:2640 (see https://github.com/bminor/binutils-gdb/blob/a6cab9afd2c81465265c8d09569e3e6ef43d2954/bfd/vms-alpha.c#L2640) 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
