>From zhoug...@mail.zgclab.edu.cn and wan...@mail.zgclab.edu.cn:
Hi, we found several crashes in c++filt(Binutils 2.42), which is the latest
version.
In detail, it contains 12 stack-buffer-overflow triggering methods.
To assist in diagnosing and resolving these issues, we have attached the POC
files along with the gdb/asan logs.
Environment:
