| Description: | Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.
Vulnerability Insight:
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 th ...
