Upgrade Debian:9
glib2.0
to version 2.50.3-2+deb9u3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream glib2.0
package and not the glib2.0
package as distributed by Debian
.
See How to fix?
for Debian:9
relevant fixed versions and status.
An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also creates the target of the symlink as an empty file, which could conceivably have security relevance if the symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents of that file correctly remain unchanged.)
