Description

An update for gvfs is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

GVFS is the GNOME Desktop Virtual File System layer that allows users to easily access local and remote data using File Transfer Protocol (FTP), Secure Shell File Transfer Protocol (SFTP), Web Distributed Authoring and Versioning (WebDAV), Common Internet File System (CIFS), Server Message Block (SMB), and other protocols. GVFS integrates with the GNOME I/O (GIO) abstraction layer.

Security Fix(es) :

  • gvfs: Incorrect authorization in admin backend allows privileged users to read and modify arbitrary files without prompting for password (CVE-2019-3827)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
