The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:1477-1 advisory.

    The openSUSE Leap 15.2 kernel was updated to receive various security and bugfixes.

    The following security bugs were fixed:

    - CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed local users to create files with an     unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by     a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose     group ownership is that group. The intended behavior was that the non-member can trigger creation of a     directory (but not a plain file) whose group ownership is that group. The non-member can escalate     privileges by making the plain file executable and SGID (bnc#1100416 bnc#1129735).
    - CVE-2021-33033: The Linux kernel had a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c     because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd.
    This leads to writing an arbitrary value (bnc#1186109 bnc#1188876).
    - CVE-2021-34556: An unprivileged BPF program can obtain sensitive information from kernel memory via a     Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of     uninitialized memory locations on the BPF stack (bnc#1188983).
    - CVE-2021-35477: An unprivileged BPF program can obtain sensitive information from kernel memory via a     Speculative Store Bypass side-channel attack because a certain preempting store operation did not     necessarily occur before a store operation that has an attacker-controlled value (bnc#1188985).
    - CVE-2021-3655: Missing size validations on inbound SCTP packets may have allowed the kernel to read     uninitialized memory (bnc#1188563 bnc#1192267).
    - CVE-2021-3715: Fixed a use-after-free in route4_change() in net/sched/cls_route.c (bsc#1190349).
    - CVE-2021-3760: Fixed a use-after-free vulnerability with the ndev->rf_conn_info object (bsc#1190067).
    - CVE-2021-3772: Invalid chunks may be used to remotely remove existing associations (bsc#1190351).
    - CVE-2021-3896: Fixed a array-index-out-bounds in detach_capi_ctr in drivers/isdn/capi/kcapi.c     (bsc#1191958).
    - CVE-2021-41864: prealloc_elems_and_freelist in kernel/bpf/stackmap.c allowed unprivileged users to     trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write (bnc#1191317).
    - CVE-2021-42008: The decode_data function in drivers/net/hamradio/6pack.c had a slab out-of-bounds write.
    Input from a process that has the CAP_NET_ADMIN capability can lead to root access (bnc#1191315).
    - CVE-2021-42252: An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c     where local attackers were able to access the Aspeed LPC control interface could overwrite memory in the     kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a certain comparison     uses values that are not memory sizes (bnc#1190479).
    - CVE-2021-42739: The firewire subsystem had a buffer overflow related to drivers/media/firewire/firedtv-     avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled bounds checking (bnc#1184673     bnc#1192036).
    - CVE-2021-42739: The firewire subsystem had a buffer overflow related to drivers/media/firewire/firedtv-     avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled bounds checking     (bsc#1184673).
    - CVE-2021-43056: It allowed a malicious KVM guest to crash the host, when the host is running on Power8,     due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S implementation bug in the handling of the SRR1 register     values (bnc#1192107).

The remote OracleVM system is missing necessary patches to address security updates:

  - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a     long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)

  - In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some     operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in     fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to     a right data structure. (CVE-2019-19448)

  - An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including     v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster     than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the     vhost_net kernel thread, resulting in a DoS scenario. (CVE-2019-3900)

  - A pivot_root race condition in fs/namespace.c in the Linux kernel 4.4.x before 4.4.221, 4.9.x before     4.9.221, 4.14.x before 4.14.178, 4.19.x before 4.19.119, and 5.x before 5.3 allows local users to cause a     denial of service (panic) by corrupting a mountpoint reference counter. (CVE-2020-12114)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a     network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP,     CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
    (CVE-2020-24586)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary     can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.
    Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an     adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)

  - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other     clients even though the sender has not yet successfully authenticated to the AP. This might be abused in     projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier     to exploit other vulnerabilities in connected clients. (CVE-2020-26139)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and     WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to     inject arbitrary data frames independent of the network configuration. (CVE-2020-26140)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation     does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can     abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-     confidentiality protocol. (CVE-2020-26141)

  - An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat     fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets,     independent of the network configuration. (CVE-2020-26142)

  - An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH. The WEP, WPA, WPA2, and     WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. An adversary can     abuse this to inject arbitrary data frames independent of the network configuration. (CVE-2020-26143)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3     implementations accept plaintext A-MSDU frames as long as the first 8 bytes correspond to a valid RFC1042     (i.e., LLC/SNAP) header for EAPOL. An adversary can abuse this to inject arbitrary network packets     independent of the network configuration. (CVE-2020-26144)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3     implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process     them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets     independent of the network configuration. (CVE-2020-26145)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WPA, WPA2, and WPA3 implementations     reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate     selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the     WEP, CCMP, or GCMP data-confidentiality protocol is used. Note that WEP is vulnerable to this attack by     design. (CVE-2020-26146)

  - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble     fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject     packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)

  - In __hidinput_change_resolution_multipliers of hid-input.c, there is a possible out of bounds write due to     a heap buffer overflow. This could lead to local escalation of privilege with no additional execution     privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-173843328References: Upstream kernel (CVE-2021-0512)

  - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on     inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)

  - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking     subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.
    This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)

  - ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.
    (CVE-2021-38160)

  - A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in     the Linux kernel through 5.13.13. (CVE-2021-40490)
