SECURITY POSTURE
GLib has a mixed security posture, evidenced by recent high-severity vulnerabilities including remote code execution and state confusion issues, alongside a concerning pattern of malware masquerading as legitimate GLib binaries in the wild.
Notable failures
- CVE-2025-14087: Remote code execution via heap corruption
- CVE-2026-58016: State confusion in D-Bus introspection XML processing
- Malware masquerading as glib-2.0-0.dll detected as Trojan.Gen
Patterns: repeated unpatched edge-device RCEs; malicious binaries masquerading as legitimate GLib components

| DATE | EVENT | SEV | SUMMARY |
|---|---|---|---|
| 2025-12-10 | CVE-2025-14087 | medium | A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings. |
| 2026-06-30 | CVE-2026-58016 | high | A flaw was found in GLib. A state confusion issue exists in g_dbus_node_info_new_for_xml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a <node> element nested within other elements like <method>, <signal>, <property> o |
