CVE ID         : CVE-2018-16428 CVE-2018-16429 CVE-2019-13012
Debian Bug     : 931234


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.

For Debian 8 "Jessie", these problems have been fixed in version
2.42.1-1+deb8u2.

We recommend that you upgrade your glib2.0 packages.
