DEBIAN-CVE-2020-26961

When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding...

CVE-2020-6111

CVE-2020-6111 affects Allen-Bradley MicroLogix 1100 PLCs (Series B FRNs 10.000–16.000). The root cause is improper handling of ICMP/IPv4 packets with invalid IPv4 length, triggering a major error that can crash the device and cause a denial-of-service (CWE-130). Reported CVSS v3 base score is 7.5...
