A locking protection bypass flaw was found in some versions of gnome-shell as shipped within CentOS Stream 8, when the "Application menu" or "Window list" GNOME extensions are enabled. This flaw allows a physical attacker who has access to a locked system to kill existing applications and start new ones as the locked user, even if the session is still locked. Se ha encontrado un fallo de omisión de la protección de bloqueo en algunas versiones de gnome-shell tal y como se distribuye en CentOS Stream 8, cuando las extensiones de GNOME "Application menu" o "Window list" están habilitadas. Este fallo permite a un atacante físico que tenga acceso a un sistema bloqueado matar las aplicaciones existentes e iniciar otras nuevas como el usuario bloqueado, incluso si la sesión sigue bloqueada • https://bugzilla.redhat.com/show_bug.cgi?id=2006285 • CWE-667: Improper Locking •
CVSS: 4.3EPSS: 0%CPEs: 4EXPL: 1CVE-2020-17489 – gnome-shell: Password from logged-out user may be shown on login screen
https://notcve.org/view.php?id=CVE-2020-17489
An issue was discovered in certain configurations of GNOME gnome-shell through 3.36.4. When logging out of an account, the password box from the login dialog reappears with the password still visible. If the user had decided to have the password shown in cleartext at login time, it is then visible for a brief moment upon a logout. (If the password were never shown in cleartext, only the password length is revealed.) Se detectó un problema en determinadas configuraciones de GNOME gnome-shell versiones hasta 3.36.4. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00028.html https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2997 https://lists.debian.org/debian-lts-announce/2020/09/msg00014.html https://security.gentoo.org/glsa/202009-08 https://usn.ubuntu.com/4464-1 https://access.redhat.com/security/cve/CVE-2020-17489 https://bugzilla.redhat.com/show_bug.cgi?id=1868418 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-522: Insufficiently Protected Credentials •
