CVSS: 5.9EPSS: 0%CPEs: 2EXPL: 0CVE-2021-4122 – cryptsetup: disable encryption via header rewrite
https://notcve.org/view.php?id=CVE-2021-4122
It was found that a specially crafted LUKS header could trick cryptsetup into disabling encryption during the recovery of the device. An attacker with physical access to the medium, such as a flash disk, could use this flaw to force a user into permanently disabling the encryption layer of that medium. Se ha detectado que un encabezado LUKS especialmente diseñada podía engañar a cryptsetup para que deshabilitara el cifrado durante la recuperación del dispositivo. Un atacante con acceso físico al medio, como un disco flash, podría usar este fallo para forzar a un usuario a deshabilitar permanentemente la capa de cifrado de ese medio. • https://access.redhat.com/security/cve/CVE-2021-4122 https://bugzilla.redhat.com/show_bug.cgi?id=2031859 https://bugzilla.redhat.com/show_bug.cgi?id=2032401 https://gitlab.com/cryptsetup/cryptsetup/-/commit/0113ac2d889c5322659ad0596d4cfc6da53e356c https://mirrors.edge.kernel.org/pub/linux/utils/cryptsetup/v2.4/v2.4.3-ReleaseNotes • CWE-345: Insufficient Verification of Data Authenticity CWE-349: Acceptance of Extraneous Untrusted Data With Trusted Data •

https://notcve.org/view.php?id=CVE-2016-4484
The Debian initrd script for the cryptsetup package 2:1.7.3-2 and earlier allows physically proximate attackers to gain shell access via many log in attempts with an invalid password. La secuencia de comandos initrd de Debian para el paquete cryptsetup 2:1.7.3-2 y versiones anteriores permite a atacantes físicamente próximos obtener acceso a shell a través de muchos intentos de inicio de sesión con una contraseña no válida. • http://hmarco.org/bugs/CVE-2016-4484/CVE-2016-4484_cryptsetup_initrd_shell.html http://www.openwall.com/lists/oss-security/2016/11/14/13 http://www.openwall.com/lists/oss-security/2016/11/15/1 http://www.openwall.com/lists/oss-security/2016/11/15/4 http://www.openwall.com/lists/oss-security/2016/11/16/6 http://www.securityfocus.com/bid/94315 https://gitlab.com/cryptsetup/cryptsetup/commit/ef8a7d82d8d3716ae9b58179590f7908981fa0cb • CWE-287: Improper Authentication •
