titleReliable Datagram Sockets (RDS) - rds_atomic_free_op NULL pointer dereference Privilege Escalation (Metasploit)

Metasploit

descriptionThis module attempts to gain root privileges on Linux systems by abusing a NULL pointer dereference in the `rds_atomic_free_op` function in the Reliable Datagram Sockets (RDS) kernel module (rds.ko). Successful exploitation requires the RDS kernel module to be loaded. If the RDS module is not blacklisted (default); then it will be loaded automatically. This exploit supports 64-bit Ubuntu Linux systems, including distributions based on Ubuntu, such as Linux Mint and Zorin OS. Target offsets are available for: Ubuntu 16.04 kernels 4.4.0 <= 4.4.0-116-generic; and Ubuntu 16.04 kernels 4.8.0 <= 4.8.0-54-generic. This exploit does not bypass SMAP. Bypasses for SMEP and KASLR are included. Failed exploitation may crash the kernel. This module has been tested successfully on various 4.4 and 4.8 kernels.

"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

CVE-2017-0861

Robb Glasser reported a potential use-after-free in the ALSA (sound)
PCM core. We believe this was not possible in practice.

CVE-2017-5715

Multiple researchers have discovered a vulnerability in various
processors supporting speculative execution, enabling an attacker
controlling an unprivileged process to read memory from arbitrary
addresses, including from the kernel and all other processes running
on the system.

This specific attack has been named Spectre variant 2
(branch target injection) and is mitigated for the x86
architecture (amd64 and i386) by using the 'retpoline'
compiler feature which allows indirect branches to be
isolated from speculative execution.

CVE-2017-13166

A bug in the 32-bit compatibility layer of the v4l2 ioctl handling
code has been found. Memory protections ensuring user-provided buffers
always point to userland memory were disabled, allowing destination
addresses to be in kernel space. On a 64-bit kernel (amd64 flavour) a
local user with access to a suitable video device can exploit this to
overwrite kernel memory, leading to privilege escalation.

CVE-2017-16526

Andrey Konovalov reported that the UWB subsystem may dereference an
invalid pointer in an error case. A local user might be able to use
this for denial of service.

CVE-2017-16911

Secunia Research reported that the USB/IP vhci_hcd driver exposed
kernel heap addresses to local users. This information could aid the
exploitation of other vulnerabilities.

CVE-2017-16912

Secunia Research reported that the USB/IP stub driver failed to
perform a range check on a received packet header field, leading to an
out-of-bounds read. A remote user able to connect to the USB/IP server
could use this for denial of service.

CVE-2017-16913

Secunia Research reported that the USB/IP stub driver failed to
perform a range check on a received packet header field, leading to
excessive memory allocation. A remote user able to connect to the
USB/IP server could use this for denial of service.

CVE-2017-16914

Secunia Research reported that the USB/IP stub driver failed to check
for an invalid combination of fields in a recieved packet, leading to
a NULL pointer dereference. A remote user able to connect to the
USB/IP server could use this for denial of service.

CVE-2017-18017

Denys Fedoryshchenko reported that the netfilter xt_TCPMSS module
failed to validate TCP header lengths, potentially leading to a
use-after-free. If this module is loaded, it could be used by a remote
attacker for denial of service or possibly for code execution.

CVE-2017-18203

Hou Tao reported that there was a race condition in creation and
deletion of device-mapper (DM) devices. A local user could potentially
use this for denial of service.

CVE-2017-18216

Alex Chen reported that the OCFS2 filesystem failed to hold a
necessary lock during nodemanager sysfs file operations, potentially
leading to a NULL pointer dereference. A local user could use this for
denial of service.

CVE-2018-1068

The syzkaller tool found that the 32-bit compatibility layer of
ebtables did not sufficiently validate offset values. On a 64-bit
kernel (amd64 flavour), a local user with the CAP_NET_ADMIN capability
could use this to overwrite kernel memory, possibly leading to
privilege escalation.

CVE-2018-1092

Wen Xu reported that a crafted ext4 filesystem image would trigger a
null dereference when mounted. A local user able to mount arbitrary
filesystems could use this for denial of service.

CVE-2018-5332

Mohamed Ghannam reported that the RDS protocol did not sufficiently
validate RDMA requests, leading to an out-of-bounds write. A local
attacker on a system with the rds module loaded could use this for
denial of service or possibly for privilege escalation.

CVE-2018-5333

Mohamed Ghannam reported that the RDS protocol did not properly handle
an error case, leading to a NULL pointer dereference. A local attacker
on a system with the rds module loaded could possibly use this for
denial of service.

CVE-2018-5750

Wang Qize reported that the ACPI sbshc driver logged a kernel heap
address. This information could aid the exploitation of other
vulnerabilities.

CVE-2018-5803

Alexey Kodanev reported that the SCTP protocol did not range-check the
length of chunks to be created. A local or remote user could use this
to cause a denial of service.

CVE-2018-6927

Li Jinyue reported that the FUTEX_REQUEUE operation on futexes did not
check for negative parameter values, which might lead to a denial of
service or other security impact.

CVE-2018-7492

The syzkaller tool found that the RDS protocol was lacking a NULL pointer check. A local attacker on a system with the rds module loaded
could use this for denial of service.

CVE-2018-7566

&#x8303;&#x9F99;&#x98DE; (Fan LongFei) reported a race condition in
the ALSA (sound) sequencer core, between write and ioctl operations.
This could lead to an out-of-bounds access or use-after-free. A local
user with access to a sequencer device could use this for denial of
service or possibly for privilege escalation.

CVE-2018-7740

Nic Losby reported that the hugetlbfs filesystem's mmap operation did
not properly range-check the file offset. A local user with access to
files on a hugetlbfs filesystem could use this to cause a denial of
service.

CVE-2018-7757

Jason Yan reported a memory leak in the SAS (Serial-Attached SCSI)
subsystem. A local user on a system with SAS devices could use this to
cause a denial of service.

CVE-2018-7995

Seunghun Han reported a race condition in the x86 MCE (Machine Check
Exception) driver. This is unlikely to have any security impact.

CVE-2018-8781

Eyal Itkin reported that the udl (DisplayLink) driver's mmap operation
did not properly range-check the file offset. A local user with access
to a udl framebuffer device could exploit this to overwrite kernel
memory, leading to privilege escalation.

CVE-2018-8822

Dr Silvio Cesare of InfoSect reported that the ncpfs client
implementation did not validate reply lengths from the server. An
ncpfs server could use this to cause a denial of service or remote
code execution in the client.

CVE-2018-1000004

Luo Quan reported a race condition in the ALSA (sound) sequencer core,
between multiple ioctl operations. This could lead to a deadlock or
use-after-free. A local user with access to a sequencer device could
use this for denial of service or possibly for privilege escalation.

CVE-2018-1000199

Andy Lutomirski discovered that the ptrace subsystem did not
sufficiently validate hardware breakpoint settings. Local users can
use this to cause a denial of service, or possibly for privilege
escalation, on x86 (amd64 and i386) and possibly other architectures.

Additionally, some mitigations for CVE-2017-5753 are included in this
release :

CVE-2017-5753

Multiple researchers have discovered a vulnerability in various
processors supporting speculative execution, enabling an attacker
controlling an unprivileged process to read memory from arbitrary
addresses, including from the kernel and all other processes running
on the system.

This specific attack has been named Spectre variant 1
(bounds-check bypass) and is mitigated by identifying
vulnerable code sections (array bounds checking followed by
array access) and replacing the array access with the
speculation-safe array_index_nospec() function.

More use sites will be added over time.

For Debian 7 'Wheezy', these problems have been fixed in version
3.2.101-1. This version also includes bug fixes from upstream versions
up to and including 3.2.101. It also fixes a regression in the procfs
hidepid option in the previous version (Debian bug #887106).

We recommend that you upgrade your linux packages.

implementations in the Linux kernel did not properly handle
zero-length inputs. A local attacker could use this to cause a denial
of service (system crash). (CVE-2017-17805)

It was discovered that the HMAC implementation did not validate the
state of the underlying cryptographic hash algorithm. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2017-17806)

It was discovered that the keyring implementation in the Linux kernel
did not properly check permissions when a key request was performed on
a tasks' default keyring. A local attacker could use this to add keys
to unauthorized keyrings. (CVE-2017-17807)

It was discovered that a race condition existed in the OCFS2 file
system implementation in the Linux kernel. A local attacker could use
this to cause a denial of service (kernel deadlock). (CVE-2017-18204)

It was discovered that the Broadcom NetXtremeII ethernet driver in the
Linux kernel did not properly validate Generic Segment Offload (GSO)
packet sizes. An attacker could use this to cause a denial of service
(interface unavailability). (CVE-2018-1000026)

It was discovered that the Reliable Datagram Socket (RDS)
implementation in the Linux kernel contained an out-of-bounds during
RDMA page allocation. An attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code.
(CVE-2018-5332)

"The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.114 to
receive various security and bugfixes. The following security bugs
were fixed :

  - CVE-2017-5715: Systems with microprocessors utilizing
    speculative execution and indirect branch prediction may
    allow unauthorized disclosure of information to an
    attacker with local user access via a side-channel
    analysis (bnc#1068032). The previous fix using CPU
    Microcode has been complemented by building the Linux
    Kernel with return trampolines aka 'retpolines'.

  - CVE-2017-15129: A use-after-free vulnerability was found
    in network namespaces code affecting the Linux kernel in
    the function get_net_ns_by_id() in
    net/core/net_namespace.c did not check for the
    net::count value after it has found a peer network in
    netns_ids idr, which could lead to double free and
    memory corruption. This vulnerability could allow an
    unprivileged local user to induce kernel memory
    corruption on the system, leading to a crash. Due to the
    nature of the flaw, privilege escalation cannot be fully
    ruled out, although it is thought to be unlikely
    (bnc#1074839).

  - CVE-2017-17712: The raw_sendmsg() function in
    net/ipv4/raw.c in the Linux kernel has a race condition
    in inet->hdrincl that leads to uninitialized stack
    pointer usage; this allowed a local user to execute code
    and gain privileges (bnc#1073229).

  - CVE-2017-17862: kernel/bpf/verifier.c in the Linux
    kernel ignored unreachable code, even though it would
    still be processed by JIT compilers. This behavior, also
    considered an improper branch-pruning logic issue, could
    possibly be used by local users for denial of service
    (bnc#1073928).

  - CVE-2017-17864: kernel/bpf/verifier.c in the Linux
    kernel mishandled states_equal comparisons between the
    pointer data type and the UNKNOWN_VALUE data type, which
    allowed local users to obtain potentially sensitive
    address information, aka a 'pointer leak (bnc#1073928).

  - CVE-2017-18017: The tcpmss_mangle_packet function in
    net/netfilter/xt_TCPMSS.c in the Linux kernel allowed
    remote attackers to cause a denial of service
    (use-after-free and memory corruption) or possibly have
    unspecified other impact by leveraging the presence of
    xt_TCPMSS in an iptables action (bnc#1074488).

  - CVE-2018-5332: In the Linux kernel the
    rds_message_alloc_sgs() function did not validate a
    value that is used during DMA page allocation, leading
    to a heap-based out-of-bounds write (related to the
    rds_rdma_extra_size function in net/rds/rdma.c)
    (bnc#1075621).

  - CVE-2018-5333: In the Linux kernel the rds_cmsg_atomic
    function in net/rds/rdma.c mishandled cases where page
    pinning fails or an invalid address is supplied, leading
    to an rds_atomic_free_op NULL pointer dereference
    (bnc#1075617).

  - CVE-2018-1000004: In the Linux kernel a race condition
    vulnerability existed in the sound system, this can lead
    to a deadlock and denial of service condition
    (bnc#1076017).

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

On a system with a driver using blk-mq (mtip32xx, null_blk, or virtio_blk), a local user might be able to use this for denial of service or possibly for privilege escalation. - CVE-2017-0861 Robb Glasser reported a potential use-after-free in the ALSA (sound) PCM core. We believe this was not possible in practice. - CVE-2017-5715 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using the

    descriptionThe SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2018-1068: Fixed flaw in the implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory (bnc#1085107). - CVE-2017-18221: The __munlock_pagevec function allowed local users to cause a denial of service (NR_MLOCK accounting corruption) via crafted use of mlockall and munlockall system calls (bnc#1084323). - CVE-2018-1066: Prevent NULL pointer dereference in fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed an attacker controlling a CIFS server to kernel panic a client that has this server mounted, because an empty TargetInfo field in an NTLMSSP setup negotiation response was mishandled during session recovery (bnc#1083640). - CVE-2017-13166: Prevent elevation of privilege vulnerability in the kernel v4l2 video driver (bnc#1072865). - CVE-2017-16911: The vhci_hcd driver allowed local attackers to disclose kernel memory addresses. Successful exploitation required that a USB device was attached over IP (bnc#1078674). - CVE-2017-15299: The KEYS subsystem mishandled use of add_key for a key that already exists but is uninstantiated, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted system call (bnc#1063416). - CVE-2017-18208: The madvise_willneed function kernel allowed local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping (bnc#1083494). - CVE-2018-7566: The ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user could have reset the pool size manually via ioctl concurrently, which may have lead UAF or out-of-bound access (bsc#1083483). - CVE-2017-18204: The ocfs2_setattr function allowed local users to cause a denial of service (deadlock) via DIO requests (bnc#1083244). - CVE-2017-16644: The hdpvr_probe function allowed local users to cause a denial of service (improper error handling and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067118). - CVE-2018-6927: The futex_requeue function allowed attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a negative wake or requeue value (bnc#1080757). - CVE-2017-16914: The

    descriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely.(CVE-2017-15129) - The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.(CVE-2017-18017) - A flaw was found in the upstream kernel Skcipher component. This vulnerability affects the skcipher_recvmsg function of the component Skcipher. The manipulation with an unknown input leads to a privilege escalation vulnerability.(CVE-2017-13215) - In the Linux kernel through 4.14.13, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size() function in

    descriptionThe SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2018-1068: Fixed flaw in the implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory (bnc#1085107). - CVE-2017-18221: The __munlock_pagevec function allowed local users to cause a denial of service (NR_MLOCK accounting corruption) via crafted use of mlockall and munlockall system calls (bnc#1084323). - CVE-2018-1066: Prevent NULL pointer dereference in fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed an attacker controlling a CIFS server to kernel panic a client that has this server mounted, because an empty TargetInfo field in an NTLMSSP setup negotiation response was mishandled during session recovery (bnc#1083640). - CVE-2017-13166: Prevent elevation of privilege vulnerability in the kernel v4l2 video driver (bnc#1072865). - CVE-2017-16911: The vhci_hcd driver allowed local attackers to disclose kernel memory addresses. Successful exploitation required that a USB device was attached over IP (bnc#1078674). - CVE-2017-15299: The KEYS subsystem mishandled use of add_key for a key that already exists but is uninstantiated, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted system call (bnc#1063416). - CVE-2017-18208: The madvise_willneed function kernel allowed local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping (bnc#1083494). - CVE-2018-7566: The ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user could have reset the pool size manually via ioctl concurrently, which may have lead UAF or out-of-bound access (bsc#1083483). - CVE-2017-18204: The ocfs2_setattr function allowed local users to cause a denial of service (deadlock) via DIO requests (bnc#1083244). - CVE-2017-16644: The hdpvr_probe function allowed local users to cause a denial of service (improper error handling and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067118). - CVE-2018-6927: The futex_requeue function allowed attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a negative wake or requeue value (bnc#1080757). - CVE-2017-16914: The
