high Nessus Plugin ID 230480
語言:
概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，供應商表示將不會修補。說明
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。- gtpudp 通訊端的 netns 卸除損毀裝置。 gtp_newlink() 將裝置連結至 dev_net(dev) 中的清單而非 src_net (在此建立 udp 通道通訊端)。即使已移除 src_net裝置仍會在 dev_net(dev) 上維持運作。接著移除 src_net 時會觸發以下問題說明。 [0] 在此範例中gtp0 是在 ns2 中建立而 udp 通訊端則是在 ns1 中建立。 ip netns add ns1 ip netns add ns2 ip -n ns1 link add netns ns2 name gtp0 type gtp role sgsn ip netns del ns1 讓我們改為將裝置連結至通訊端的 netns。現在 gtp_net_exit_batch_rtnl() 需要另一個 netdev 重複才能移除 netns 中的所有 gtp 裝置。 [0]: ref_tracker: net notrefcnt@000000003d6e7d05 在 sk_alloc 有 1/2 使用者 (./include/net/net_namespace.h:345 net/core/sock.c:2236) inet_create (net/ipv4/af_inet.c:326) net/ipv4/af_inet.c:252) __sock_create (net/socket.c:1558) udp_sock_create4 (net/ipv4/udp_tunnel_core.c:18) gtp_create_sock (./include/net/udp_tunnel.h:59 drivers/net/gtp .c:1423) gtp_create_sockets (drivers/net/gtp.c:1447) gtp_newlink (drivers/net/gtp.c:1507) rtnl_newlink (net/core/rtnetlink.c:3786 net/core/rtnetlink.c:3897 net /core/rtnetlink.c:4012) rtnetlink_rcv_msg (net/core/rtnetlink.c:6922) netlink_rcv_skb (net/netlink/af_netlink.c:2542) netlink_unicast (net/netlink/af_netlink.c:1321 net/netlink/af_netlink。 c:1347) netlink_sendmsg (net/netlink/af_netlink.c:1891)____sys_sendmsg (net/socket.c:711 net/socket.c:726 net/socket.c:2583) ___sys_sendmsg (net/socket.c:2639) __sys_sendmsg (net/socket.c:2669) do_syscall_64 (arch/x86/entry/common.c:52 arch/x86/entry/common.c:83) 警告 CPU1 PID: 60 at lib/ref_tracker.c: 179重新f_tracker_dir_exit (lib/ref_tracker.c:179) 模組連結於 CPU1 UID0 PID60 通訊 kworker/u16:2 未受污染的 6.13.0-rc5-00147-g4c1224501e9d #5 硬體名稱QEMU 標準 PC ( i440FX + PIIX, 1996)、BIOS rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org 2014 年 4 月 1 日工作佇列
