This update for the Linux Kernel 3.12.51-60_25 fixes the several issues.
These security issues were fixed:
- CVE-2016-4470: The key_reject_and_link function in security/keys/key.c
in the Linux kernel did not ensure that a certain data structure is
initialized, which allowed local users to cause a denial of service
(system crash) via vectors involving a crafted keyctl request2 command
(bsc#984764).
- CVE-2016-1583: The ecryptfs_privileged_open function in
fs/ecryptfs/kthread.c in the Linux kernel allowed local users to gain
privileges or cause a denial of service (stack memory consumption) via
vectors involving crafted mmap calls for /proc pathnames, leading to
recursive pagefault handling (bsc#983144).
- CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel
incorrectly relied on the write system call, which allowed local users
to cause a denial of service (kernel memory write operation) or possibly
have unspecified other impact via a uAPI interface (bsc#980883).
- CVE-2016-0758: Integer overflow in lib/asn1_decoder.c in the Linux
kernel allowed local users to gain privileges via crafted ASN.1 data
(bsc#980856).
- CVE-2015-8019: The skb_copy_and_csum_datagram_iovec function in
net/core/datagram.c in the Linux kernel did not accept a length
argument, which allowed local users to cause a denial of service (memory
corruption) or possibly have unspecified other impact via a write system
call followed by a recvmsg system call (bsc#979078).
- CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in
the Linux kernel allowed attackers to cause a denial of service (panic)
via an ASN.1 BER file that lacks a public key, leading to mishandling by
the public_key_verify_signature function in
crypto/asymmetric_keys/public_key.c (bsc#979074).
- CVE-2015-8816: The hub_activate function in drivers/usb/core/hub.c in
the Linux kernel did not properly maintain a hub-interface data
structure, which allowed physically proximate attackers to cause a
denial of service (invalid memory access and system crash) or possibly
have unspecified other impact by unplugging a USB hub device
(bsc#979064).
- CVE-2016-3134: The netfilter subsystem in the Linux kernel did not
validate certain offset fields, which allowed local users to gain
privileges or cause a denial of service (heap memory corruption) via an
IPT_SO_SET_REPLACE setsockopt call (bsc#971793).
This non-security issue was fixed:
- bsc#973570: The fix for CVE-2013-7446 introduced a bug that could have
possibly lead to a softlockup.
