Exim before 4.97.1 allows SMTP smuggling in certain PIPELINING/CHUNKING 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 Exim supports <LF>.<CR><LF> but some other popular e-mail servers do not. Exim hasta 4.97 permite el contrabando SMTP en ciertas configuraciones. • http://www.openwall.com/lists/oss-security/2023/12/24/1 http://www.openwall.com/lists/oss-security/2023/12/25/1 http://www.openwall.com/lists/oss-security/2023/12/29/2 http://www.openwall.com/lists/oss-security/2024/01/01/1 http://www.openwall.com/lists/oss-security/2024/01/01/2 http://www.openwall.com/lists/oss-security/2024/01/01/3 https://bugs.exim.org/show_bug.cgi?id=3063 https://bugzilla.redhat.com/show_bug.cgi?id=2255852 https:/ • CWE-345: Insufficient Verification of Data Authenticity •

https://notcve.org/view.php?id=CVE-2023-6918
A flaw was found in the libssh implements abstract layer for message digest (MD) operations implemented by different supported crypto backends. The return values from these were not properly checked, which could cause low-memory situations failures, NULL dereferences, crashes, or usage of the uninitialized memory as an input for the KDF. In this case, non-matching keys will result in decryption/integrity failures, terminating the connection. Se encontró un fallo en la capa abstracta de implementación de libssh para operaciones de resumen de mensajes (MD) implementadas por diferentes backends criptográficos compatibles. Los valores de retorno de estos no se verificaron correctamente, lo que podría causar fallas en situaciones de poca memoria, desreferencias NULL, fallas o uso de la memoria no inicializada como entrada para el KDF. • https://access.redhat.com/errata/RHSA-2024:2504 https://access.redhat.com/errata/RHSA-2024:3233 https://access.redhat.com/security/cve/CVE-2023-6918 https://bugzilla.redhat.com/show_bug.cgi?id=2254997 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LZQVUHWVWRH73YBXUQJOD6CKHDQBU3DM https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/MKQRBF3DWMWPH36LBCOBUTSIZRTPEZXB https://www.libssh.org/2023/12/18/libssh-0-10-6-and-libssh- • CWE-252: Unchecked Return Value •
CVSS: 5.9EPSS: 96%CPEs: 79EXPL: 1CVE-2023-48795 – ssh: Prefix truncation attack on Binary Packet Protocol (BPP)
https://notcve.org/view.php?id=CVE-2023-48795
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.
