Affected Products:

openSUSE Leap 42.1

______________________________________________________________________________

 

An update that solves 19 vulnerabilities and has 17 fixes

is now available.

 

Description:

 

 

The openSUSE Leap 42.1 kernel was updated to 4.1.26 to receive various

security and bugfixes.

 

The following security bugs were fixed:

- CVE-2016-1583: Prevent the usage of mmap when the lower file system does

not allow it. This could have lead to local privilege escalation when

ecryptfs-utils was installed and /sbin/mount.ecryptfs_private was setuid

(bsc#983143).

- CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel

incorrectly relies on the write system call, which allows local users to

cause a denial of service (kernel memory write operation) or possibly

have unspecified other impact via a uAPI interface. (bsc#979548)

- CVE-2016-4805: Use-after-free vulnerability in

drivers/net/ppp/ppp_generic.c in the Linux kernel allowed local users to

cause a denial of service (memory corruption and system crash,

or spinlock) or possibly have unspecified other impact by removing a

network namespace, related to the ppp_register_net_channel and

ppp_unregister_channel functions. (bsc#980371).

- CVE-2016-4951: The tipc_nl_publ_dump function in net/tipc/socket.c in

the Linux kernel did not verify socket existence, which allowed local

users to cause a denial of service (NULL pointer dereference and system

crash) or possibly have unspecified other impact via a dumpit

operation. (bsc#981058).

- CVE-2016-5244: An information leak vulnerability in function

rds_inc_info_copy of file net/rds/recv.c was fixed that might have

leaked kernel stack data. (bsc#983213).

- CVE-2016-4580: The x25_negotiate_facilities function in

net/x25/x25_facilities.c in the Linux kernel did not properly initialize

a certain data structure, which allowed attackers to

obtain sensitive information from kernel stack memory via an X.25 Call

Request. (bsc#981267).

- CVE-2016-0758: Tags with indefinite length could have corrupted pointers

in asn1_find_indefinite_length (bsc#979867).

- 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 (bnc#963762).

- CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the

Linux kernel allowed local users to bypass intended AF_UNIX socket

permissions or cause a denial of service (panic) via crafted epoll_ctl

calls (bnc#955654).

- 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 (bnc#971126).

- CVE-2016-3672: The arch_pick_mmap_layout function in arch/x86/mm/mmap.c

in the Linux kernel did not properly randomize the legacy base address,

which made it easier for local users to defeat the intended restrictions

on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism

for a setuid or setgid program, by disabling stack-consumption resource

limits (bnc#974308).

- CVE-2016-4482: A kernel information leak in the usbfs devio connectinfo

was fixed, which could expose kernel stack memory to userspace.

(bnc#978401).

- CVE-2016-4485: A kernel information leak in llc was fixed (bsc#978821).

- CVE-2016-4486: A kernel information leak in rtnetlink was fixed, where 4

uninitialized bytes could leak to userspace (bsc#978822).

- CVE-2016-4557: A use-after-free via double-fdput in

replace_map_fd_with_map_ptr() was fixed, which could allow privilege

escalation (bsc#979018).

- CVE-2016-4565: When the "rdma_ucm" infiniband module is loaded, local

attackers could escalate their privileges (bsc#979548).

- CVE-2016-4569: A kernel information leak in the ALSA timer via events

via snd_timer_user_tinterrupt that could leak information to userspace

was fixed (bsc#979213).

- CVE-2016-4578: A kernel information leak in the ALSA timer via events

that could leak information to userspace was fixed (bsc#979879).

- CVE-2016-4581: If the first propogated mount copy was being a slave it

could oops the kernel (bsc#979913)
