nm-new testcases
Hello,
I detected the memory leak and dead loop problems through fuzz testing, which I
think be a vulnerability.
The configuration of binutils is:
$ ./configure --disable-shared && make -j
and compiled with gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0
I use the program nm-new in ~/binutils-gdb/binutils/nm-new with parameter "-C
./dead_loop_input", and after waiting 1 hours, the program neither giving any
outputs nor terminating. What is more, the program nm-new occupied all the
memory.
The testcase that trigger such results are in the attachment.
Thanks & Best Regards
