CVE-2024-2397 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libpcap package and not the libpcap package as distributed by RHEL.
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.
