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` or `arg`. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service.\n\n## Affected\n\n- `glib < 2.88.1`\n- `enterprise_linux = 6.0`\n- `enterprise_linux = 7.0`\n- `enterprise_linux = 8.0`\n- `enterprise_linux = 9.0`\n- `enterprise_linux = 10.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `glib 2.88.1`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
