概要
遠端 RockyLinux 主機缺少一個或多個安全性更新。說明
遠端 RockyLinux 8 主機已安裝受到多個弱點影響的套件如 RLSA-2021:1762 公告中所提及。* libvirtqemu_agent.c 中的 qemuAgentGetInterfaces() 發生雙重釋放 (CVE-2020-25637)
* QEMU在 hw/pci/msix.c 中 msix_table_mmio_write() 中的堆積緩衝區溢位 (CVE-2020-27821)
* QEMUideatapi處理讀取命令時發生 OOB 存取 (CVE-2020-29443)
* QEMUblock/iscsi.c 的 iscsi_aio_ioctl_cb() 中發生堆積緩衝區溢位可能導致資訊洩漏 (CVE-2020-11947)
* QEMU在 hw/net/net_tx_pkt.c 的 net_tx_pkt_add_raw_fragment() 中發生可連線宣告失敗 (CVE-2020-16092)
* QEMUhw/net/e1000e_core.c 的 e1000e_write_packet_to_guest() 中發生無限迴圈 (CVE-2020-25707)
* QEMU透過 hw/usb/hcd-ehci.c 中的 usb_packet_unmap() 發生的宣告失敗 (CVE-2020-25723)
* QEMUe1000enull 封包描述符號情況下的無限迴圈情形 (CVE-2020-28916)
* QEMUslirp處理 ARP/NCSI 封包時發生超出邊界存取 (CVE-2020-29129、 CVE-2020-29130)
Tenable 已直接從 RockyLinux 安全公告擷取前置描述區塊。
請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼作出判斷。
