05 Aug 2022 — This advisory documents the impact of an internally found vulnerability in Arista EOS for security ACL bypass. The impact of this vulnerability is that the security ACL drop rule might be bypassed if a NAT ACL rule filter with permit action matches the packet flow. This could allow a host with an IP address in a range that matches the range allowed by a NAT ACL and a range denied by a Security ACL to be forwarded incorrectly as it should have been denied by the Security ACL. This can enable an ACL bypass. E... • https://www.arista.com/en/support/advisories-notices/security-advisory/15862-security-advisory-0078 • CWE-284: Improper Access Control •

CVE-2020-25684 – dnsmasq: loose address/port check in reply_query() makes forging replies easier for an off-path attacker
https://notcve.org/view.php?id=CVE-2020-25684
19 Jan 2021 — A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in the forward.c:reply_query() if the reply destination address/port is used by the pending forwarded queries. However, it does not use the address/port to retrieve the exact forwarded query, substantially reducing the number of attempts an attacker on the network would have to perform to forge a reply and get it accepted by dnsmasq. This issue contrasts with RFC5452, which specifies a query's attrib... • https://bugzilla.redhat.com/show_bug.cgi?id=1889686 • CWE-358: Improperly Implemented Security Check for Standard •

CVE-2020-25685 – dnsmasq: loose query name check in reply_query() makes forging replies easier for an off-path attacker
https://notcve.org/view.php?id=CVE-2020-25685
19 Jan 2021 — A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in forward.c:reply_query(), which is the forwarded query that matches the reply, by only using a weak hash of the query name. Due to the weak hash (CRC32 when dnsmasq is compiled without DNSSEC, SHA-1 when it is) this flaw allows an off-path attacker to find several different domains all having the same hash, substantially reducing the number of attempts they would have to perform to forge a reply an... • https://bugzilla.redhat.com/show_bug.cgi?id=1889688 • CWE-326: Inadequate Encryption Strength •
