Insight
Insight
Various minor issues have been addressed in the GLib library. GLib is a useful general-purpose C library used by projects such as GTK+, GIMP, and GNOME. CVE-2018-16428 In GNOME GLib, g_markup_parse_context_end_parse() in gmarkup.c had a NULL pointer dereference. CVE-2018-16429 GNOME GLib had an out-of-bounds read vulnerability in g_markup_parse_context_parse() in gmarkup.c, related to utf8_str(). CVE-2019-13012 The keyfile settings backend in GNOME GLib (aka glib2.0) before created 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 did not properly restrict directory (and file) permissions. Instead, for directories, 0777 permissions were used, for files, default file permissions were used. This issue is similar to CVE-2019-12450.
