  script_tag(name:"insight", value:"The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2015-8970: crypto/algif_skcipher.c in the Linux kernel did not
 verify that a setkey operation has been performed on an AF_ALG socket
 before an accept system call is processed, which allowed local users to
 cause a denial of service (NULL pointer dereference and system crash)
 via a crafted application that did not supply a key, related to the
 lrw_crypt function in crypto/lrw.c (bnc#1008374).
- CVE-2017-5551: Clear S_ISGID on tmpfs when setting posix ACLs
 (bsc#1021258).
- CVE-2016-7097: The filesystem implementation in the Linux kernel
 preserves the setgid bit during a setxattr call, which allowed local
 users to gain group privileges by leveraging the existence of a setgid
 program with restrictions on execute permissions (bnc#995968).
- 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-2004-0230: TCP, when using a large Window Size, made it easier for
 remote attackers to guess sequence numbers and cause a denial of service
 (connection loss) to persistent TCP connections by repeatedly injecting
 a TCP RST packet, especially in protocols that use long-lived
 connections, such as BGP (bnc#969340).
- CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the
 Linux kernel did not validate the relationship between the minimum
 fragment length and the maximum packet size, which allowed local users
 to gain privileges or cause a denial of service (heap-based buffer
 overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831).
- CVE-2016-8399: An elevation of privilege vulnerability in the kernel
 networking subsystem could have enabled a local malicious application to
 execute arbitrary code within the context of the kernel bnc#1014746).
- 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).
- CVE-2012-6704: 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 ... [Please see the references for more information on the vulnerabilities]");
