概要
遠端 Red Hat 主機缺少 libvirt 的安全性更新。:說明
遠端 Redhat Enterprise Linux 9 主機上安裝的套件受到 RHSA-2023: 3715 公告中提及的一個弱點影響。- 在 libvirt 中發現一個弱點。此安全性缺陷是因為重複查詢 SR-IOV PCI 裝置的功能所導致，該行為會暴露因無法在父項結構的 g_autoptr 清理中釋放 virPCIVirtualFunction 陣列而造成的記憶體洩漏。(CVE-2023-2700)
請注意，Nessus 並未測試此問題，而是僅依據應用程式自我報告的版本號碼作出判斷。
解決方案
依據 RHSA-2023: 3715 中的指引更新 RHEL libvirt 套件。另請參閱
