Severity: normal
Exploitable: remote
Date: 2020-07-27
Bug(s): #725880
ID: 202007-50

Synopsis

GLib Networking was not properly verifying TLS certificates in all
circumstances, possibly allowing an integrity/confidentiality compromise.


Background

Network-related giomodules for glib

Affected Packages

Package: net-libs/glib-networking
Vulnerable: < 2.62.4
Unaffected: >= 2.62.4
Architectures: All supported architectures


Description

GTlsClientConnection skips hostname verification of the server’s TLS
certificate if the application fails to specify the expected server
identity.


Impact

There may be a breach of integrity or confidentiality in connections
made using GLib Networking.


Workaround

There is no known workaround at this time.

Resolution

All GLib Networking users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=net-libs/glib-networking-2.62.4"
