Hello!
CVE-2021-28153 11.03.21 23:15
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.)
Another CVE just out,
See: https://gitlab.gnome.org/GNOME/glib/-/issues/2325
We need to backport another patch again it seems?
Thank you,
Léo

Thanks. I backported the upstream fix, and pushed it to 'master' in
commit 5a06b83fc92710c5846a83bbf49f0ea84c8ecec2.
