Glib: glib: buffer underflow in gvariant parser leads to heap corruption

GLib provides the core application building blocks for libraries and applications written in C. It provides the core object system used in GNOME, the main loop implementation, and a large set of utility functions for strings and common data structures. Security Fix(es): * glib: GLib: Buffer underflow in GVariant parser leads to heap corruption (CVE-2025-14087) * glib: buffer over-read in glib/gvariant-serialiser.c via gvs_tuple_is_normal() (CVE-2026-58010) * glib: out-of-bounds read in glib/gdatetime.c:g_date_time_get_ymd via invalid GDateTime (CVE-2026-58011) * glib: buffer over-read in g_regex_replace() via glib/gregex.c:string_append() and g_utf8_next_char() (CVE-2026-58012) * glib: buffer over-read in glib/giochannel.c via "g_io_channel_read_line_backend" (CVE-2026-58013) * glib: off-by-one error in glib/gkeyfile.c via "g_key_file_get_locale_string_list" (CVE-2026-58014) * glib: path traversal in glib/gio/gdbusauthmechanismsha1.c via keyring_lookup_entry and mechanism_client_data_receive (CVE-2026-58015) * glib: integer underflow in gio/gdbusintrospection.c via "g_dbus_node_info_new_for_xml" (CVE-2026-58016) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
