Four-Year-Old Critical #Linux Wi-Fi Bug Allows System Compromise

A patch is currently under revision but has not yet been incorporated into the Linux kernel.

A critical Linux bug has been discovered that could allow attackers to fully compromise vulnerable machines. A fix has been proposed but has not yet been incorporated into the Linux kernel.

The flaw (CVE-2019-17666), which was classified as critical in severity, exists in the “rtlwifi” driver, which is a software component used to allow certain #Realtek Wi-Fi modules, used in Linux devices, to communicate with the Linux operating system.

DLA-1965-1 nfs-utils -- LTS security update

Date Reported:19 Oct 2019
Affected Packages:nfs-utils
Vulnerable:Yes
Security database references:
In the Debian bugtracking system: Bug 940848.
In Mitre's CVE dictionary: CVE-2019-3689.

More information:
In the nfs-utils package, providing support files for Network File System (NFS) including the rpc.statd daemon, the directory /var/lib/nfs is owned by statd:nogroup. This directory contains files owned and managed by root. If statd is compromised, it can therefore trick processes running with root privileges into creating/overwriting files anywhere on the system.

For Debian 8 Jessie, this problem has been fixed in version 1.2.8-9+deb8u1.

We recommend that you upgrade your nfs-utils packages.
