An update that fixes 9 vulnerabilities is now available.

 

Description:

 

This update for the Linux Kernel 3.12.49-11.1 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.
