SUSE SLES12 Security Update : kernel (SUSE-SU-2018:2858-1)

High Nessus Plugin ID 117800

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 12 SP3 azure kernel was updated to 4.4.155
to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-13093: Prevent NULL pointer dereference and panic in
lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a
corrupted xfs image. This occured because of a lack of proper
validation that cached inodes are free during allocation (bnc#1100001)

CVE-2018-13095: Prevent denial of service (memory corruption and BUG)
that could have occurred for a corrupted xfs image upon encountering
an inode that is in extent format, but has more extents than fit in
the inode fork (bnc#1099999)

CVE-2018-13094: Prevent OOPS that may have occured for a corrupted xfs
image after xfs_da_shrink_inode() is called with a NULL bp
(bnc#1100000)

CVE-2018-12896: Prevent integer overflow in the POSIX timer code that
was caused by the way the overrun accounting works. Depending on
interval and expiry time values, the overrun can be larger than
INT_MAX, but the accounting is int based. This basically made the
accounting values, which are visible to user space via
timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a
local user to cause a denial of service (signed integer overflow) via
crafted mmap, futex, timer_create, and timer_settime system calls
(bnc#1099922)

CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status
that could have been used by local attackers to read kernel memory
(bnc#1107689)

CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local
attackers to use a incorrect bounds check in the CDROM driver
CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)

CVE-2018-6555: The irda_setsockopt function allowed local users to
cause a denial of service (ias_object use-after-free and system crash)
or possibly have unspecified other impact via an AF_IRDA socket
(bnc#1106511)

CVE-2018-6554: Prevent memory leak in the irda_bind function that
allowed local users to cause a denial of service (memory consumption)
by repeatedly binding an AF_IRDA socket (bnc#1106509)

CVE-2018-1129: A flaw was found in the way signature calculation was
handled by cephx authentication protocol. An attacker having access to
ceph cluster network who is able to alter the message payload was able
to bypass signature checks done by cephx protocol (bnc#1096748)

CVE-2018-1128: It was found that cephx authentication protocol did not
verify ceph clients correctly and was vulnerable to replay attack. Any
attacker having access to ceph cluster network who is able to sniff
packets on network can use this vulnerability to authenticate with
ceph service and perform actions allowed by ceph service (bnc#1096748)

CVE-2018-10938: A crafted network packet sent remotely by an attacker
forced the kernel to enter an infinite loop in the cipso_v4_optptr()
function leading to a denial-of-service (bnc#1106016)

CVE-2018-15572: The spectre_v2_select_mitigation function did not
always fill RSB upon a context switch, which made it easier for
attackers to conduct userspace-userspace spectreRSB attacks
(bnc#1102517)

CVE-2018-10902: Protect against concurrent access to prevent double
realloc (double free) in snd_rawmidi_input_params() and
snd_rawmidi_output_status(). A malicious local attacker could have
used this for privilege escalation (bnc#1105322).

CVE-2018-9363: Prevent buffer overflow in hidp_process_report
(bsc#1105292)

CVE-2018-10883: A local user could have caused an out-of-bounds write
in jbd2_journal_dirty_metadata(), a denial of service, and a system
crash by mounting and operating on a crafted ext4 filesystem image
(bsc#1099863)

CVE-2018-10879: A local user could have caused a use-after-free in
ext4_xattr_set_entry function and a denial of service or unspecified
other impact by renaming a file in a crafted ext4 filesystem image
(bsc#1099844)

CVE-2018-10878: A local user could have caused an out-of-bounds write
and a denial of service or unspecified other impact by mounting and
operating a crafted ext4 filesystem image (bsc#1099813)

CVE-2018-10876: A use-after-free was possible in
ext4_ext_remove_space() function when mounting and operating a crafted
ext4 image (bsc#1099811)

CVE-2018-10877: Prevent out-of-bound access in the
ext4_ext_drop_refs() function when operating on a crafted ext4
filesystem image (bsc#1099846)

CVE-2018-10881: A local user could have caused an out-of-bound access
in ext4_get_group_info function, a denial of service, and a system
crash by mounting and operating on a crafted ext4 filesystem image
(bsc#1099864)

CVE-2018-10882: A local user could have caused an out-of-bound write,
a denial of service, and a system crash by unmounting a crafted ext4
filesystem image (bsc#1099849)

CVE-2018-10880: Prevent stack-out-of-bounds write in the ext4
filesystem code when mounting and writing to a crafted ext4 image in
ext4_update_inline_data(). An attacker could have used this to cause a
system crash and a denial of service (bsc#1099845)

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution

To install this SUSE Security Update use the SUSE recommended
installation methods like YaST online_update or 'zypper patch'.

Alternatively you can run the command listed for your product :

SUSE Linux Enterprise Software Development Kit 12-SP3:zypper in -t
patch SUSE-SLE-SDK-12-SP3-2018-2004=1

SUSE Linux Enterprise Server 12-SP3:zypper in -t patch
