Name of the Vulnerable Software and Affected Versions GNOME GLib versions 2.15.0 through 2.61.1

Description The issue is related to the file copy fallback function in the gio/gfile.c file, which does not properly restrict file permissions during a copy operation. Instead of using restricted permissions, it uses default permissions. This could potentially allow a remote attacker to gain unauthorized access to protected information.

Recommendations For versions 2.15.0 through 2.61.1, consider updating to a version where this issue is fixed, as the use of default permissions during file copy operations could lead to security issues. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
