openSUSE Security Update: Security update for the Linux Kernel ______________________________________________________________________________ Announcement ID: openSUSE-SU-2017:0458-1 Rating: important References: #1003077 #1007886 #1009969 #1010444 #1011820 #1013273 #1013531 #1013540 #1013542 #1017589 #1017710 #1019658 #1019660 #1019784 #1020214 #1020381 #1021258 #983348 #987333 #987576 Cross-References: CVE-2016-10088 CVE-2016-10147 CVE-2016-7117 CVE-2016-7917 CVE-2016-8645 CVE-2016-9793 CVE-2016-9806 CVE-2017-5551 Affected Products: openSUSE Leap 42.1 ______________________________________________________________________________ An update that solves 8 vulnerabilities and has 12 fixes is now available. Description: The openSUSE Leap 42.1 kernel to 4.1.38 to receive various security and bugfixes. The following security bugs were fixed: - CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077). - CVE-2017-5551: tmpfs: Fixed a bug that could have allowed users to set setgid bits on files they don't down (bsc#1021258). - CVE-2016-10147: crypto/mcryptd.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) by using an AF_ALG socket with an incompatible algorithm, as demonstrated by mcryptd(md5) (bnc#1020381). - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bnc#1017710). - CVE-2016-7917: The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux kernel did not check whether a batch message's length field is large enough, which allowed local users to obtain sensitive information from kernel memory or cause a denial of service (infinite loop or out-of-bounds read) by leveraging the CAP_NET_ADMIN capability (bnc#1010444). - CVE-2016-8645: The TCP stack in the Linux kernel mishandled skb truncation, which allowed local users to cause a denial of service (system crash) via a crafted application that made sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c (bnc#1009969). - CVE-2016-9806: Race condition in the netlink_dump function in net/netlink/af_netlink.c in the Linux kernel allowed local users to cause a denial of service (double free) or possibly have unspecified other impact via a crafted application that made sendmsg system calls, leading to a free operation associated with a new dump that started earlier than anticipated (bnc#1013540 1017589). - CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531 1013542). The following non-security bugs were fixed: - PCI: generic: Fix pci_remap_iospace() failure path (bsc#1019658). - bcache: partition support: add 16 minors per bcacheN device (bsc#1019784). - bnx2x: Correct ringparam estimate when DOWN (bsc#1020214). - clk: xgene: Do not call __pa on ioremaped address (bsc#1019660). - kABI workaround for 4.1.37 mount changes (stable-4.1.37). - kABI: reintroduce sk_filter (bsc#1009969). - kabi/severities: Ignore inode_change_ok change It's renamed in 4.1.37 to setattr_prepare() - mpi: Fix NULL ptr dereference in mpi_powm() [ver #3] (bsc#1011820). - net: introduce __sock_queue_rcv_skb() function (bsc#1009969). - netback: correct array index (bsc#983348). - netfront: do not truncate grant references. - netfront: use correct linear area after linearizing an skb (bsc#1007886). - reiserfs: fix race in prealloc discard (bsc#987576). - rose: limit sk_filter trim to payload (bsc#1009969). - scsi: bfa: Increase requested firmware version to 3.2.5.1 (bsc#1013273). - xenbus: correctly signal errors from xenstored_local_init() (luckily none so far). - xenbus: do not invoke ->is_ready() for most device states (bsc#987333).
