CVE-2026-58016— GNOME GLib 数字错误漏洞

一分钟漏洞结论

影响对象
GNOME GLib
利用判断
尚无明确在野利用证据,仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本;无法立即升级时,限制受影响服务暴露并加强监测。

GNOME glib是GNOME基金会开源的一个通用的、可移植的实用程序库。提供了许多有用的数据类型、宏、类型转换、字符串实用程序、文件实用程序、主循环抽象等。 GLib 2.88.1之前版本存在数字错误漏洞,该漏洞源于在g_dbus_node_info_new_for_xml()函数处理格式错误的D-Bus introspection XML时存在状态混淆问题,具体为<node>元素嵌套在<method>、<signal>、<property>或<arg>等其他元素内,可能导致无符号整数溢出并引发越界读

Vulnerability Title
Glib: integer underflow in gio/gdbusintrospection.c via "g_dbus_node_info_new_for_xml"
来源: CVE Program / CVE List V5
Vulnerability Description
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` or `arg`. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service.
