Hello,
I detected the following crash exception through fuzz testing, which I think
might be a vulnerability.
The configuration of bin-utils is:
$ CFLAGS="-fsanitize=address" CXXFLAGS="-fsanitize=address" ./configure
--disable-shared && make -j
Here is the stack trace by address sanitizer:
==74962==ERROR: AddressSanitizer: heap-buffer-overflow on address
