______________________________________________________________________________
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)
