Error description
We have a few calls in copyRemoteStats() like strcat() that do not check boundaries of local variables before copying or appending data. This can lead to stack corruptions. An example top of before the signal handler stack would be: #7 <signal handler called> #8 0x00007fdf3a1f9577 in __intel_sse2_strcat() #9 0x00007fdf3a1f45c9 in copyRemoteStats() ... There is no workaround known.
