Bug ID: 21813
Summary: Additional undefined behavior and crashes
Product: binutils
Version: 2.30 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: ned at forallsecure dot com
Target Milestone: ---

5 testcases with asan output
I've found 5 more bugs in objdump master branch.
These bugs repro for me when building for all targets with a recent version of
clang and AddressSanitizer and running them with `./objdump -xg testcase` (one
crash requires debug output).
If any don't reproduce, let me know and I can try to identify another testcase
or help identify the root cause. I've included `asan_output` with my stacktrace
for each test.
I have investigated alpha-heap-overflow, and there the fix is to check that
`PRIV (recrd.rec_size) > test_len` before reading the remaining record.
Cheers,
Ned
