APAR status

  • Closed as fixed if next.

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.
