Title:	Debian LTS: Security Advisory for linux (DLA-1930-1)
Summary:	The remote host is missing an update for the 'linux'; package(s) announced via the DLA-1930-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux' package(s) announced via the DLA-1930-1 advisory. Vulnerability Insight: Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2016-10905 A race condition was discovered in the GFS2 file-system implementation, which could lead to a use-after-free. On a system using GFS2, a local attacker could use this for denial of service (memory corruption or crash) or possibly for privilege escalation. CVE-2018-20976 It was discovered that the XFS file-system implementation did not correctly handle some mount failure conditions, which could lead to a use-after-free. The security impact of this is unclear. CVE-2018-21008 It was discovered that the rsi wifi driver did not correctly handle some failure conditions, which could lead to a use-after- free. The security impact of this is unclear. CVE-2019-0136 It was discovered that the wifi soft-MAC implementation (mac80211) did not properly authenticate Tunneled Direct Link Setup (TDLS) messages. A nearby attacker could use this for denial of service (loss of wifi connectivity). CVE-2019-9506 Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered a weakness in the Bluetooth pairing protocols, dubbed the 'KNOB attack'. An attacker that is nearby during pairing could use this to weaken the encryption used between the paired devices, and then to eavesdrop on and/or spoof communication between them. This update mitigates the attack by requiring a minimum encryption key length of 56 bits. CVE-2019-14814, CVE-2019-14815, CVE-2019-14816 Multiple bugs were discovered in the mwifiex wifi driver, which could lead to heap buffer overflows. A local user permitted to configure a device handled by this driver could probably use this for privilege escalation. CVE-2019-14821 Matt Delco reported a race condition in KVM's coalesced MMIO facility, which could lead to out-of-bounds access in the kernel. A local attacker permitted to access /dev/kvm could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. CVE-2019-14835 Peter Pi of Tencent Blade Team discovered a missing bounds check in vhost_net, the network back-end driver for KVM hosts, leading to a buffer overflow when the host begins live migration of a VM. An attacker in control of a VM could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation on the host. CVE-2019-15117 Hui Peng and Mathias Payer reported a missing bounds check in the usb-audio driver's descriptor parsing code, leading to a buffer over-read. An attacker able to add USB devices could possibly use this to cause a deni ... Description truncated. Please see the references for more information. Affected Software/OS: 'linux' package(s) on Debian Linux. Solution: For Debian 8 'Jessie', these problems have been fixed in version 3.16.74-1. We recommend that you upgrade your linux packages.
