In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix signed integer overflow in l2tp_ip6_sendmsg When len >= INT_MAX - transhdrlen, ulen = len + transhdrlen will be overflow. To fix, we can follow what udpv6 does and subtract the transhdrlen from the max.

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

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ipv6: Fix signed integer overflow in l2tp_ip6_sendmsg When len >= INT_MAX - transhdrlen, ulen = len +     transhdrlen will be overflow. To fix, we can follow what udpv6 does and subtract the transhdrlen from the     max. (CVE-2022-49727)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of kernel installed on the remote host is prior to 5.4.201-111.359. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-028 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    drm/plane: Move range check for format_count earlier (CVE-2021-47659)

    Due to the small table perturb size, a memory leak flaw was found in the Linux kernel's TCP source port     generation algorithm in the net/ipv4/tcp.c function. This flaw allows an attacker to leak information and     may cause a denial of service. (CVE-2022-1012)

    A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-     component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

    A use-after-free vulnerability was found in the Linux kernel's Netfilter subsystem in     net/netfilter/nf_tables_api.c. This flaw allows a local attacker with user access to cause a privilege     escalation issue. (CVE-2022-1966)

    A flaw was found in hw. Incomplete cleanup of multi-core shared buffers for some Intel(r) Processors may     allow an authenticated user to enable information disclosure via local access. (CVE-2022-21123)

    A flaw was found in hw. Incomplete cleanup of microarchitectural fill buffers on some Intel(r) Processors     may allow an authenticated user to enable information disclosure via local access. (CVE-2022-21125)

    A flaw was found in hw. Incomplete cleanup in specific special register write operations for some     Intel Processors may allow an authenticated user to enable information disclosure via local access.
    (CVE-2022-21166)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote host is prior to 4.14.285-215.501. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1813 advisory.

    A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in     the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or     CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494)

    An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c function in     RPCRDMA_HDRLEN_MIN (7) (in rpcrdma_max_call_header_size, rpcrdma_max_reply_header_size). This flaw allows     an attacker with normal user privileges to leak kernel information. (CVE-2022-0812)

    Due to the small table perturb size, a memory leak flaw was found in the Linux kernel's TCP source port     generation algorithm in the net/ipv4/tcp.c function. This flaw allows an attacker to leak information and     may cause a denial of service. (CVE-2022-1012)

    A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-     component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

    A use-after-free vulnerability was found in the Linux kernel's Netfilter subsystem in     net/netfilter/nf_tables_api.c. This flaw allows a local attacker with user access to cause a privilege     escalation issue. (CVE-2022-1966)

    A flaw was found in hw. Incomplete cleanup of multi-core shared buffers for some Intel(r) Processors may     allow an authenticated user to enable information disclosure via local access. (CVE-2022-21123)

    A flaw was found in hw. Incomplete cleanup of microarchitectural fill buffers on some Intel(r) Processors     may allow an authenticated user to enable information disclosure via local access. (CVE-2022-21125)

    A flaw was found in hw. Incomplete cleanup in specific special register write operations for some     Intel Processors may allow an authenticated user to enable information disclosure via local access.
    (CVE-2022-21166)

    net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create     user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to     a use-after-free. (CVE-2022-32250)

    The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are     used. (CVE-2022-32296)

    An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer     overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point     registers. (CVE-2022-32981)
