CVE-2004-0057 is a medium-severity flaw (CVSS 5.0) affecting tcpdump. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
The rawprint function in the ISAKMP decoding routines (print-isakmp.c) for tcpdump 3.8.1 and earlier allows remote attackers to cause a denial of service (segmentation fault) via malformed ISAKMP packets that cause invalid "len" or "loc" values to be used in a loop, a different vulnerability than CVE-2003-0989.
Why this priority
- EPSS top 7%: very likely to be exploited
A fixed release or distro patch exists.
