Arch Linux Security Advisory ASA-202010-9 ========================================= Severity: High Date : 2020-10-18 CVE-ID : CVE-2020-12351 CVE-2020-12352 CVE-2020-24490 Package : linux-hardened Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1251 Summary ======= The package linux-hardened before version 5.8.16.a-1 is vulnerable to multiple issues including information disclosure, privilege escalation and denial of service. Resolution ========== Upgrade to 5.8.16.a-1. # pacman -Syu "linux-hardened>=5.8.16.a-1" The problems have been fixed upstream in version 5.8.16.a. Workaround ========== None. Description =========== - CVE-2020-12351 (privilege escalation) A flaw was found in the way the Linux kernel Bluetooth implementation handled L2CAP packets with A2MP CID. A remote attacker in adjacent range could use this flaw to crash the system causing denial of service or potentially execute arbitrary code on the system by sending a specially crafted L2CAP packet. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. - CVE-2020-12352 (information disclosure) An information leak flaw was found in the way the Linux kernel's Bluetooth stack implementation handled initialization of stack memory when handling certain AMP packets. A remote attacker in adjacent range could use this flaw to leak small portions of stack memory on the system by sending a specially crafted AMP packets. The highest threat from this vulnerability is to data confidentiality. - CVE-2020-24490 (denial of service) A heap buffer overflow flaw was found in the way the Linux kernel’s Bluetooth implementation processed extended advertising report events. This flaw allows a remote attacker in an adjacent range to crash the system, causing a denial of service or to potentially execute arbitrary code on the system by sending a specially crafted Bluetooth packet. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Impact ====== A remote unauthenticated attacker in range is able to execute arbitrary code, disclose information or DoS the system through bluetooth.
