This type value is uninitialized upon encountering certain error conditions. This value is used as an array index for dereferencing, which leads to an OOPS and eventually a DoS of knfsd and a soft-lockup of the whole system (bsc#1046202)\n- CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel allowed remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c (bsc#1046191).\n- CVE-2017-2636: Race condition in drivers/tty/n_hdlc.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (double free) by setting the HDLC line discipline (bsc#1027575).\n- CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel is too late in checking whether an overwrite of an skb data structure may occur, which allowed local users to cause a denial of service (system crash) via crafted system calls (bsc#1042892).\n- CVE-2017-9077: The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bsc#1042364).\n- CVE-2017-8890: The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bsc#1038564).\n","id":"SUSE-SU-2017:2065-1","modified":"2017-08-07T08:08:28Z","published":"2017-08-07T08:08:28Z","references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2017/suse-su-20172065-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1027575"},{"type":"REPORT","url":"https://bugzilla.suse.com/1038564"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042364"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042892"},{"type":"REPORT","url":"https://bugzilla.suse.com/1046191"},{"type":"REPORT","url":"https://bugzilla.suse.com/1046202"},{"type":"REPORT","url":"https://bugzilla.suse.com/1046206"},{"type":"REPORT","url":"https://bugzilla.suse.com/1050751"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-2636"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-7533"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-7645"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-8797"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-8890"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-9077"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-9242"}],"related":["CVE-2017-2636","CVE-2017-7533","CVE-2017-7645","CVE-2017-8797","CVE-2017-8890","CVE-2017-9077","CVE-2017-9242"],"summary":"Security update for Linux Kernel Live Patch 4 for SLE 12 SP2"}
