CVE-2025-3360

A flaw was found in GLib. An integer overflow and buffer under-read occur when parsing a long invalid ISO 8601 timestamp with the g_date_time_new_from_iso8601() function.

GLib is a bundle of three (formerly five) low-level system libraries written in C and developed mainly by GNOME. GLib's code was separated from GTK, so it can be used by software other than GNOME and has been developed in parallel ever since.

Security Fix(es):

Glib prior to 2.82.5 is vulnerable to integer overflow and buffer under-read when parsing a very long invalid iso 8601 timestamp with g_date_time_new_from_iso8601(). (CVE-2025-3360) Buffer under-read on glib through glib/gfileutils.c via get_tmp_file(). (CVE-2025-7039) Integer overflow in g_escape_uri_string(). (CVE-2025-13601) Buffer underflow in gvariant parser leads to heap corruption. (CVE-2025-14087) Integer overflow in glib gio attribute escaping causes heap buffer overflow. (CVE-2025-14512) Denial of service via integer overflow in g_buffered_input_stream_peek(). (CVE-2026-0988)

These are all security issues fixed in the gio-branding-upstream-2.84.1-2.1 package on the GA media of openSUSE Tumbleweed.

It was discovered that GLib incorrectly handled escaping URI strings. An attacker could use this issue to cause GLib to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2025-13601)

It was discovered that GLib incorrectly parsed certain GVariants. An attacker could use this issue to cause GLib to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2025-14087)

It was discovered that GLib incorrectly parsed certain long invalid ISO 8601 timestamps. An attacker could possibly use this issue to cause GLib to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2025-3360)

It was discovered that GLib incorrectly handled GString memory operations. An attacker could use this issue to cause GLib to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.04. (CVE-2025-6052)

It was discovered that GLib incorrectly handled creating temporary files. An attacker could possibly use this issue to access unauthorized data. This issue only affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 25.04. (CVE-2025-7039)
