NASL family Debian Local Security Checks NASL id DEBIAN_DSA-4187.NASL description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2015-9016 Ming Lei reported a race condition in the multiqueue block layer (blk-mq). On a system with a driver using blk-mq (mtip32xx, null_blk, or virtio_blk), a local user might be able to use this for denial of service or possibly for privilege escalation. - CVE-2017-0861 Robb Glasser reported a potential use-after-free in the ALSA (sound) PCM core. We believe this was not possible in practice. - CVE-2017-5715 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using the last seen 2020-06-01 modified 2020-06-02 plugin id 109517 published 2018-05-02 reporter This script is Copyright (C) 2018-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/109517 title Debian DSA-4187-1 : linux - security update (Spectre) NASL family SuSE Local Security Checks NASL id SUSE_SU-2018-1221-1.NASL description The SUSE Linux Enterprise 12 GA LTSS kernel was updated to receive various security and bugfixes.

This flaw is known as Spectre Variant 4. A local attacker could use this to expose sensitive information, including kernel memory. (CVE-2018-3639) Jan H. Schonherr discovered that the Xen subsystem did not properly handle block IO merges correctly in some situations. An attacker in a guest vm could use this to cause a denial of service (host crash) or possibly gain administrative privileges in the host. (CVE-2017-12134) It was discovered that the Bluetooth HIP Protocol implementation in the Linux kernel did not properly validate HID connection setup information. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-13220) It was discovered that a buffer overread vulnerability existed in the keyring subsystem of the Linux kernel. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2017-13305) It was discovered that the netlink subsystem in the Linux kernel did not properly restrict observations of netlink messages to the appropriate net namespace. A local attacker could use this to expose sensitive information (kernel netlink traffic). (CVE-2017-17449) It was discovered that a race condition existed in the i8042 serial device driver implementation in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-18079) It was discovered that a race condition existed in the Device Mapper component of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-18203) It was discovered that a race condition existed in the OCFS2 file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service (kernel deadlock).

(CVE-2017-18221) Silvio Cesare discovered a buffer overwrite existed in the NCPFS implementation in the Linux kernel. A remote attacker controlling a malicious NCPFS server could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-8822).
