ovn: ovn: Heap Over-Read in ICMP Error Response Generation - security issue

When generating an ICMP Destination Unreachable or Packet Too Big response, the handler copies a portion of the original packet into the ICMP error body using the IP header's self-declared total length iptotlen for IPv4, ip6plen for IPv6 without validating it against the actual packet buffer size...

SUSE CVE-2021-31401

An issue was discovered in tcprcv in nptcp.c in HCC embedded InterNiche 4.0.1. The TCP header processing code doesn't sanitize the value of the IP total length field header length + data length. With a crafted IP packet, an integer overflow occurs whenever the value of the IP data length is...
