Background ========== USBView is a tool to display the topology of devices on the USB bus. Affected packages ================= Package Vulnerable Unaffected ----------------- ------------ ------------ app-admin/usbview < 2.2 >= 2.2 Description =========== A vulnerability has been discovered in usbview. Please review the CVE identifier referenced below for details. Impact ====== USBView allows some local users (e.g., ones logged in via SSH) to execute arbitrary code as root because certain Polkit settings (e.g., allow_any=yes) for pkexec disable the authentication requirement. Code execution can, for example, use the --gtk-module option. Workaround ========== There is no known workaround at this time. Resolution ========== All USBView users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/usbview-2.2" References ========== [ 1 ] CVE-2022-23220 https://nvd.nist.gov/vuln/detail/CVE-2022-23220 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202310-15 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
