https://notcve.org/view.php?id=CVE-2020-8037
The ppp decapsulator in tcpdump 4.9.3 can be convinced to allocate a large amount of memory. El ppp decapsulator en tcpdump versión 4.9.3 puede ser convencido para que asigne una gran cantidad de memoria A flaw was found in tcpdump while printing PPP packets captured in a pcap file or coming from the network. This flaw allows a remote attacker to send specially crafted packets that, when printed, can lead the application to allocate a large amount of memory, resulting in a denial of service. The highest threat from this vulnerability is to system availability. • http://seclists.org/fulldisclosure/2021/Apr/51 https://github.com/the-tcpdump-group/tcpdump/commit/32027e199368dad9508965aae8cd8de5b6ab5231 https://lists.debian.org/debian-lts-announce/2020/11/msg00018.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F2MX34MJIUJQGL6CMEPLTKFOOOC3CJ4Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LWDBONZVLC6BAOR2KM376DJCM4H3FERV https://support.apple.com/kb/HT212325 https://support.apple.com/kb/HT212326 h • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
