Description SMASH SMASH 2024-04-15 15:01:06 UTC 
Due to a bug in packet data buffers management, the PPP printer in tcpdump can enter an infinite loop when reading a crafted DLT_PPP_SERIAL .pcap savefile.  This problem does not affect any tcpdump release, but it affected the git master branch from 2023-06-05 to 2024-03-21.
