Debian LTS Advisory ([SECURITY] [DLA 1827-1] gvfs security update)

Published: 2019-06-20 02:00:11
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:L/Au:N/C:P/I:P/A:P

Summary:
The remote host is missing an update for the 'gvfs' Linux Distribution Package(s) announced via the DSA-1827-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
Simon McVittie discovered a flaw in gvfs, the Gnome Virtual File System. The gvfsd daemon opened a private D-Bus server socket without configuring an authorization rule. A local attacker could connect to this server socket and issue D-Bus method calls. (Note that the server socket only accepts a single connection, so the attacker would have to discover the server and connect to the socket before its owner does.)

Affected Versions:
'gvfs' Linux Distribution Package(s) on Debian Linux.

Recommendations:
For Debian 8 'Jessie', this problem has been fixed in version 1.22.2-1+deb8u1. We recommend that you upgrade your gvfs Linux Distribution Packages.

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
