Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - Avahi 是一種可透過 mDNS/DNS-SD 通訊協定套件在區域網路上協助探索服務的系統。在 0.9-rc4 版之前任何無權限的本機使用者皆可透過傳送具有衝突發布旗標的單一 D-Bus 方法呼叫來損毀 avahi-daemon。此問題已在 0.9-rc4 版中修補。
    (CVE-2026-34933)

請注意，Nessus 依賴供應商報告的套件存在。

According to the versions of the avahi packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol     suite. Prior to version 0.9-rc4, any unprivileged local user can crash avahi-daemon by sending a single     D-Bus method call with conflicting publish flags. This issue has been patched in version     0.9-rc4.(CVE-2026-34933)

    Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol     suite. In versions 0.9rc2 and below, avahi-daemon can be crashed via a segmentation fault by sending an     unsolicited mDNS response containing a recursive CNAME record, where the alias and canonical name point to     the same domain (e.g., 'h.local' as a CNAME for 'h.local'). This causes unbounded recursion in the     lookup_handle_cname function, leading to stack exhaustion. The vulnerability affects record browsers where     AVAHI_LOOKUP_USE_MULTICAST is set explicitly, which includes record browsers created by resolvers used by     nss-mdns. This issue is patched in commit 78eab31128479f06e30beb8c1cbf99dd921e2524.(CVE-2026-24401)

Tenable has extracted the preceding description block directly from the EulerOS avahi security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
