TITLE

Bluetooth Core Specification Authorization problem vulnerability

DESCRIPTION

Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 202209-16 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: BlueZ: Multiple Vulnerabilities Date: September 29, 2022 Bugs: #797712, #835077 ID: 202209-16 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been discovered in BlueZ, the worst of which could result in arbitrary code execution.

An attacker could possibly use this to expose sensitive information. (CVE-2021-45485) It was discovered that the per cpu memory allocator in the Linux kernel could report kernel pointers via dmesg. An attacker could use this to expose sensitive information or in conjunction with another kernel vulnerability. (CVE-2018-5995) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 ESM: linux-image-4.4.0-1103-kvm 4.4.0-1103.112 linux-image-4.4.0-1138-aws 4.4.0-1138.152 linux-image-4.4.0-222-generic 4.4.0-222.255 linux-image-4.4.0-222-lowlatency 4.4.0-222.255 linux-image-aws 4.4.0.1138.143 linux-image-generic 4.4.0.222.229 linux-image-kvm 4.4.0.1103.101 linux-image-lowlatency 4.4.0.222.229 linux-image-virtual 4.4.0.222.229 Ubuntu 14.04 ESM: linux-image-4.4.0-1102-aws 4.4.0-1102.107 linux-image-4.4.0-222-generic 4.4.0-222.255~14.04.1 linux-image-4.4.0-222-lowlatency 4.4.0-222.255~14.04.1 linux-image-aws 4.4.0.1102.100 linux-image-generic-lts-xenial 4.4.0.222.193 linux-image-lowlatency-lts-xenial 4.4.0.222.193 linux-image-virtual-lts-xenial 4.4.0.222.193 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
