OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. OpenSSH hasta 9.6, cuando se utilizan tipos comunes de DRAM, podría permitir row hammer attacks (para omitir la autenticación) porque el valor entero de autenticado en mm_answer_authpassword no resiste cambios de un solo bit. NOTA: esto es aplicable a un determinado modelo de amenaza de ubicación conjunta entre atacante y víctima en el que el atacante tiene privilegios de usuario. • https://access.redhat.com/security/cve/CVE-2023-51767 https://arxiv.org/abs/2309.02545 https://bugzilla.redhat.com/show_bug.cgi?id=2255850 https://github.com/openssh/openssh-portable/blob/8241b9c0529228b4b86d88b1a6076fb9f97e4a99/auth-passwd.c#L77 https://github.com/openssh/openssh-portable/blob/8241b9c0529228b4b86d88b1a6076fb9f97e4a99/monitor.c#L878 https://security.netapp.com/advisory/ntap-20240125-0006 https://ubuntu.com/security/CVE-2023-51767 •
CVSS: 5.3EPSS: 0%CPEs: 8EXPL: 6CVE-2023-51764 – postfix: SMTP smuggling vulnerability
https://notcve.org/view.php?id=CVE-2023-51764
Postfix through 3.8.5 allows SMTP smuggling unless configured with smtpd_data_restrictions=reject_unauth_pipelining and smtpd_discard_ehlo_keywords=chunking (or certain other options that exist in recent versions). 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 Postfix supports <LF>.<CR><LF> but some other popular e-mail servers do not. To prevent attack variants (by always disallowing <LF> without <CR>), a different solution is required, such as the smtpd_forbid_bare_newline=yes option with a Postfix minimum version of 3.5.23, 3.6.13, 3.7.9, 3.8.4, or 3.9. • https://github.com/duy-31/CVE-2023-51764 https://github.com/eeenvik1/CVE-2023-51764 https://github.com/Double-q1015/CVE-2023-51764 https://github.com/d4op/CVE-2023-51764-POC 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/2024/05/09/3 https://access.redhat.com/security/cve/CVE-2023-51764 https://bugzilla.redhat.com/show_bug.cgi?id=2255563 http • CWE-345: Insufficient Verification of Data Authenticity CWE-451: User Interface (UI) Misrepresentation of Critical Information •

CVSS: 8.8EPSS: 0%CPEs: 10EXPL: 0CVE-2023-6546 – Kernel: gsm multiplexing race condition leads to privilege escalation
https://notcve.org/view.php?id=CVE-2023-6546
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system. Se encontró una condición de ejecución en el multiplexor tty GSM 0710 en el kernel de Linux. Este problema ocurre cuando dos subprocesos ejecutan GSMIOC_SETCONF ioctl en el mismo descriptor de archivo tty con la disciplina de línea gsm habilitada y puede provocar un problema de use after free en una estructura gsm_dlci al reiniciar gsm mux. • http://www.openwall.com/lists/oss-security/2024/04/10/18 http://www.openwall.com/lists/oss-security/2024/04/10/21 http://www.openwall.com/lists/oss-security/2024/04/11/7 http://www.openwall.com/lists/oss-security/2024/04/11/9 http://www.openwall.com/lists/oss-security/2024/04/12/1 http://www.openwall.com/lists/oss-security/2024/04/12/2 http://www.openwall.com/lists/oss-security/2024/04/16/2 http://www.openwall.com/lists/oss-security/20 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
