NVD Description

Note: Versions mentioned in the description apply only to the upstream libpcap package and not the libpcap package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

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.
