24 Dec 2023 — sendmail through 8.17.2 allows SMTP smuggling in certain configurations. Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because sendmail supports <LF>.<CR><LF> but some other popular e-mail servers do not. This is resolved in 8.18 and later versions with 'o' in srv_features. sendmail hasta al menos 8.14.7 permite el contrabando SMTP en ciertas configuraciones. • http://www.openwall.com/lists/oss-security/2023/12/24/1 • CWE-345: Insufficient Verification of Data Authenticity •

23 Mar 2022 — ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at ... • https://alpaca-attack.com • CWE-295: Improper Certificate Validation •
