CVE-2019-13012: Gnome Glib

High severity, CVSS 7.5. EPSS: 3.2% chance of exploitation in the next 30 days.

The keyfile settings backend in GNOME GLib (aka glib2.0) before 2.60.0 creates directories using g_file_make_directory_with_parents (kfsb->dir, NULL, NULL) and files using g_file_replace_contents (kfsb->file, contents, length, NULL, FALSE, G_FILE_CREATE_REPLACE_DESTINATION, NULL, NULL, NULL). Consequently, it does not properly restrict directory (and file) permissions. Instead, for directories, 0777 permissions are used; for files, default file permissions are used. This is similar to CVE-2019-12450.

Affected products

• Gnome Glib: from 2.0.0, before 2.59.1 (fixed in 2.59.1)
