It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-039 advisory.

    Amazon Linux has been made aware of a potential Branch Target Injection (BTI) issue (sometimes referred to     as Spectre variant 2). This is a known cross-domain transient execution attack where a third party may     seek to cause a disclosure gadget to be speculatively executed after an indirect branch prediction.
    Generally, actors who attempt transient execution attacks do not have access to the data on the hosts they     attempt to access (e.g. where privilege-level isolation is in place). For such attacks to succeed, actors     need to be able to run code on the (virtual) machine hosting the data in which they are interested.

    To mitigate this issue, Amazon Linux recommends that customers disable unprivileged eBPF.  This     configuration, having the unprivileged eBPF disabled, is the current default for most Linux distributions     and as of this advisory, is also the default for all Amazon Linux kernels.

    Specific mitigations for various CPUs are listed below.

    Intel CPUs:For Intel CPUs, this applies to all instance types that have CPUs with eIBRS support. They     are:*6i* (all sizes), c5d.metal, c5.metal, g4dn.metal, i3en.metal, m5*.metal, r5*.metal

    Vectors outside of unprivileged eBPF are not currently known, and Intel recommends disabling unprivileged     BPF, as mentioned above. However, optionally enabling spectre_v2=eibrs,lfence on Linux kernel command     line on the instance types mentioned above, would provide additional protection.

    AMD CPUs:As part of the investigation triggered by this issue, AMD now recommends using a different     software mitigation inside the Linux kernel, which the Amazon Linux kernel is enabling by default. This     means that the Linux kernel will use the generic retpoline software mitigation, instead of the specialized     AMD one, on AMD instances (*5a*). This is done by default, and no administrator action is needed.

    ARM CPUs:The Amazon Linux kernel now enables, by default, a software mitigation for this issue, on all     ARM-based EC2 instance types.

    Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may     allow an authorized user to potentially enable information disclosure. (CVE-2022-0001)

    Non-transparent sharing of branch predictor within a context in some Intel(r) Processors may allow an     authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Insufficient control flow management for the Intel(R) 82599 Ethernet Controllers and Adapters may allow an     authenticated user to potentially enable denial of service via local access. (CVE-2021-33061)

  - Product: AndroidVersions: Android kernelAndroid ID: A-173788806References: Upstream kernel     (CVE-2021-39713)

  - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may     allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)

  - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an     authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)

  - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This     flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a     leak of internal kernel information. (CVE-2022-1353)

  - The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount     of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will     access the freed drm_vgem_gem_object. (CVE-2022-1419)

  - An issue was discovered in the Linux Kernel from 4.18 to 4.19, an improper update of sock reference in TCP     pacing can lead to memory/netns leak, which can be used by remote clients. (CVE-2022-1678)

  - In mmc_blk_read_single of block.c, there is a possible way to read kernel heap memory due to uninitialized     data. This could lead to local information disclosure if reading from an SD card that triggers errors,     with no additional execution privileges needed. User interaction is not needed for exploitation.Product:
    AndroidVersions: Android kernelAndroid ID: A-216481035References: Upstream kernel (CVE-2022-20008)

  - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation,     aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to     influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive     information. (CVE-2022-23960)

  - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions. (CVE-2022-29581)

  - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers     to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)

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

The version of kernel installed on the remote host is prior to 4.14.268-139.500. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2022-1571 advisory.

    A buffer overflow flaw in the Linux kernel BPF subsystem was found in the way users run BPF with long jump     over an instruction sequence where inner instructions require substantial expansions into multiple BPF     instructions. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2018-25020)

    A denial of service flaw was found in fuse_do_getattr in fs/fuse/dir.c in the kernel side of the FUSE     filesystem in the Linux kernel. A local user could use this flaw to crash the system. (CVE-2020-36322)

    A flaw was found in the hanging of mounts in the Linux kernel's NFS4 subsystem where remote servers are     unreachable for the client during migration of data from one server to another (during trunking     detection). This flaw allows a remote NFS4 server (if the client is connected) to starve the resources,     causing a denial of service. The highest threat from this vulnerability is to system availability.
    (CVE-2021-38199)

    An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

    Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may     allow an authorized user to potentially enable information disclosure. (CVE-2022-0001)

    A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends     a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
    This flaw allows a remote user to crash the system or possibly escalate their privileges if they have     access to the TIPC network. (CVE-2022-0435)

    A NULL pointer dereference was found in the Linux kernel's UDF file system functionality in the way the     user triggers the udf_file_write_iter function for a malicious UDF image. This flaw allows a local user to     crash the system. (CVE-2022-0617)

    A flaw was found in the Linux kernel. When an application tries to open a directory (using the O_DIRECTORY     flag) in a mounted NFS filesystem, a lookup operation is performed. If the NFS server returns a file as a     result of the lookup, the NFS filesystem returns an uninitialized file descriptor instead of the expected     ENOTDIR value. This flaw leads to the kernel's data leak into the userspace. (CVE-2022-24448)References to     CVE-2021-26401, CVE-2021-26341 and CVE-2022-23960 have been added after the original release of this     advisory, however those vulnerabilities were fixed by the packages referenced by this advisory's initial     release on 2022-03-07

    References to CVE-2022-0847 have been removed after the original release of this advisory, as we have     determined that the code within kernel versions prior to 5.8 is not affected by CVE-2022-0847.
