The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2021-0706 advisory.

  - A flaw was found in podman before 1.7.0. File permissions for non-root users running in a privileged     container are not correctly checked. This flaw can be abused by a low-privileged user inside the container     to access any other file in the container, even if owned by the root user inside the container. It does     not allow to directly escape the container, though being a privileged container means that a lot of     security features are disabled when running the container. The highest threat from this vulnerability is     to data confidentiality and integrity as well as system availability. (CVE-2021-20188)

  - A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI     command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a     Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable     content directly into memory. The table is further loaded and executed by the kernel, defeating its Secure     Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability     is to data confidentiality and integrity, as well as system availability. (CVE-2020-14372)

  - A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a     module used as a dependency without checking if any other dependent module is still loaded leading to a     use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot     protections. The highest threat from this vulnerability is to data confidentiality and integrity as well     as system availability. (CVE-2020-25632)

  - A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are     read with very little bounds checking and assumes the USB device is providing sane values. If properly     exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a     bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality     and integrity as well as system availability. (CVE-2020-25647)

  - A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied     command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage,     without sufficient bounds checking. If the function is called with a command line that references a     variable with a sufficiently large payload, it is possible to overflow the stack buffer, corrupt the stack     frame and control execution which could also circumvent Secure Boot protections. The highest threat from     this vulnerability is to data confidentiality and integrity as well as system availability.
    (CVE-2020-27749)

  - A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking     allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent     SecureBoot protections after proper triage about grub's memory layout. The highest threat from this     vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-27779)

  - A flaw was found in grub2 in versions prior to 2.06. The option parser allows an attacker to write past     the end of a heap-allocated buffer by calling certain commands with a large number of specific short forms     of options. The highest threat from this vulnerability is to data confidentiality and integrity as well as     system availability. (CVE-2021-20225)

  - A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code performs     a length calculation on the assumption that expressing a quoted single quote will require 3 characters,     while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each     quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as     well as system availability. (CVE-2021-20233)

  - Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to a denial of service attack when too     many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file     descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept     new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is     configured, then this lead to an excessive memory usage and cause the system to run out of memory.
    (CVE-2021-22883)

  - Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to DNS rebinding attacks as the     whitelist includes localhost6. When localhost6 is not present in /etc/hosts, it is just an ordinary     domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or     can spoof its responses, the DNS rebinding protection can be bypassed by using the localhost6 domain. As     long as the attacker uses the localhost6 domain, they can still apply the attack described in     CVE-2018-7160. (CVE-2021-22884)

The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-9079 advisory.

  - An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations     often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success     or failure of each one is reported to the backend driver, and the backend driver then loops over the     results, performing follow-up actions based on the success or failure of each operation. Unfortunately,     when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively     implying their success from the success of related batch elements. In other cases, errors resulting from     one batch element lead to further batch elements not being inspected, and hence successful ones to not be     possible to properly unmap upon error recovery. Only systems with Linux backends running in PV mode are     vulnerable. Linux backends run in HVM / PVH modes are not vulnerable. This affects arch/*/xen/p2m.c and     drivers/xen/gntdev.c. (CVE-2021-26932)

  - In kbd_keycode of keyboard.c, there is a possible out of bounds write due to a missing bounds check. 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-144161459     (CVE-2020-0431)

  - An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service requests to     the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be     encountered. In one case, an error encountered earlier might be discarded by later processing, resulting     in the caller assuming successful mapping, and hence subsequent operations trying to access space that     wasn't mapped. In another case, internal state would be insufficiently updated, preventing safe recovery     from the error. This affects drivers/block/xen-blkback/blkback.c. (CVE-2021-26930)

  - An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and SCSI     backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially     being at least under the influence of guests (such as out of memory conditions), it isn't correct to     assume a plain bug. Memory allocations potentially causing such crashes occur only when Linux is running     in PV mode, though. This affects drivers/block/xen-blkback/blkback.c and drivers/xen/xen-scsiback.c.

  - If Content Security Policy blocked frame navigation, the full destination of a redirect served in the     frame was reported in the violation report; as opposed to the original frame URI. This could be used to     leak sensitive information contained in such URIs.  (CVE-2021-23968)

  - As specified in the W3C Content Security Policy draft, when creating a violation report, User agents need     to ensure that the source file is the URL requested by the page, pre-redirects.

  - Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 are vulnerable to a use-after-free bug in its     TLS implementation. When writing to a TLS enabled socket, node::StreamBase::Write calls     node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. If the DoWrite method     does not return an error, this object is passed back to the caller as part of a StreamWriteResult     structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other     exploits. (CVE-2020-8265)

  - This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application     that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited     further depending on the context. (CVE-2020-7788)

  - Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 are vulnerable to a use-after-free bug in its     TLS implementation. When writing to a TLS enabled socket, node::StreamBase::Write calls     node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. If the DoWrite method     does not return an error, this object is passed back to the caller as part of a StreamWriteResult     structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other     exploits. (CVE-2020-8265)

  - Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 allow two copies of a header field in an HTTP     request (for example, two Transfer-Encoding header fields). In this case, Node.js identifies the first     header field and ignores the second. This can lead to HTTP Request Smuggling. (CVE-2020-8287)

  - A Node.js application that allows an attacker to trigger a DNS request for a host of their choice could     trigger a Denial of Service in versions < 15.2.1, < 14.15.1, and < 12.19.1 by getting the application to     resolve a DNS record with a larger number of responses. This is fixed in 15.2.1, 14.15.1, and 12.19.1.
    (CVE-2020-8277)

  - This affects the package y18n before 3.2.2, 4.0.1 and 5.0.5. PoC by po6ix: const y18n = require('y18n')();
    y18n.setLocale('__proto__'); y18n.updateLocale({polluted: true}); console.log(polluted); // true     (CVE-2020-7774)

  - An issue was discovered in ajv.validate() in Ajv (aka Another JSON Schema Validator) 6.12.2. A carefully     crafted JSON schema could be provided that allows execution of other code by prototype pollution. (While     untrusted schemas are recommended against, the worst case of an untrusted schema should be a denial of     service, not execution of code.) (CVE-2020-15366)

  - This affects the package npm-user-validate before 1.0.1. The regex that validates user emails took     exponentially longer to process long input strings beginning with @ characters. (CVE-2020-7754)

  - mixin-deep is vulnerable to Prototype Pollution in versions before 1.3.2 and version 2.0.0. The function     mixin-deep could be tricked into adding or modifying properties of Object.prototype using a constructor     payload. (CVE-2019-10746)

  - set-value is vulnerable to Prototype Pollution in versions lower than 3.0.1. The function mixin-deep could     be tricked into adding or modifying properties of Object.prototype using any of the constructor, prototype     and _proto_ payloads. (CVE-2019-10747)

  - This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application     that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited     further depending on the context. (CVE-2020-7788)

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-9067 advisory.

  - An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations     often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success     or failure of each one is reported to the backend driver, and the backend driver then loops over the     results, performing follow-up actions based on the success or failure of each operation. Unfortunately,     when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively     implying their success from the success of related batch elements. In other cases, errors resulting from     one batch element lead to further batch elements not being inspected, and hence successful ones to not be     possible to properly unmap upon error recovery. Only systems with Linux backends running in PV mode are     vulnerable. Linux backends run in HVM / PVH modes are not vulnerable. This affects arch/*/xen/p2m.c and     drivers/xen/gntdev.c. (CVE-2021-26932)

  - An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service requests to     the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be     encountered. In one case, an error encountered earlier might be discarded by later processing, resulting     in the caller assuming successful mapping, and hence subsequent operations trying to access space that     wasn't mapped. In another case, internal state would be insufficiently updated, preventing safe recovery     from the error. This affects drivers/block/xen-blkback/blkback.c. (CVE-2021-26930)

  - An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and SCSI     backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially     being at least under the influence of guests (such as out of memory conditions), it isn't correct to     assume a plain bug. Memory allocations potentially causing such crashes occur only when Linux is running     in PV mode, though. This affects drivers/block/xen-blkback/blkback.c and drivers/xen/xen-scsiback.c.

  - nss: CHACHA20-POLY1305 decryption with undersized tag leads to out-of-bounds read (CVE-2020-12403)

  - When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which     leaked partial information about the nonce used during signature generation. Given an electro-magnetic     trace of a few signature generations, the private key could have been computed. This vulnerability affects     Firefox < 80 and Firefox for Android < 80. (CVE-2020-6829)

  - When converting coordinates from projective to affine, the modular inversion was not performed in constant     time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox < 80     and Firefox for Android < 80. (CVE-2020-12400)

    drivers/tty/tty_jobctrl.c allows a use-after-free attack against TIOCSPGRP, aka CID-54ffccbf053b.
    (CVE-2020-29661)

  - A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem     allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate     privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as     system availability. (CVE-2020-14351)

  - A flaw in the way reply ICMP packets are limited in the Linux kernel functionality was found that allows     to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypassing source     port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly     integrity, because software that relies on UDP source port randomization are indirectly affected as well.
    Kernel versions before 5.10 may be vulnerable to this issue. (CVE-2020-25705)

  - An improper file permissions vulnerability affects Kata Containers prior to 1.11.5. When using a     Kubernetes hostPath volume and mounting either a file or directory into a container as readonly, the     file/directory is mounted as readOnly inside the container, but is still writable inside the guest. For a     container breakout situation, a malicious guest can potentially modify or delete files/directories     expected to be read-only. (CVE-2020-28914)

  - An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before     5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its     'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the     QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the     privileges of the QEMU process on the host. (CVE-2020-14364)

  - In QEMU through 5.0.0, an assertion failure can occur in the network packet processing. This issue affects     the e1000e and vmxnet3 network devices. A malicious guest user/process could use this flaw to abort the     QEMU process on the host, resulting in a denial of service condition in net_tx_pkt_add_raw_fragment in     hw/net/net_tx_pkt.c. (CVE-2020-16092)

  - hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address     in an msi-x mmio operation. (CVE-2020-13754)

  - In QEMU 5.0.0 and earlier, megasas_lookup_frame in hw/scsi/megasas.c has an out-of-bounds read via a     crafted reply_queue_head field from a guest OS user. (CVE-2020-13362)

  - hw/net/tulip.c in QEMU 4.2.0 has a buffer overflow during the copying of tx/rx buffers because the frame     size is not validated against the r/w data length. (CVE-2020-11102)

  - hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This     occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or     process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or     potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555.

  - address_space_map in exec.c in QEMU 4.2.0 can trigger a NULL pointer dereference related to BounceBuffer.
    (CVE-2020-13659)

  - sd_wp_addr in hw/sd/sd.c in QEMU 4.2.0 uses an unvalidated address, which leads to an out-of-bounds read     during sdhci_write() operations. A guest OS user can crash the QEMU process. (CVE-2020-13253)

  - A flaw was found in QEMU in the implementation of the Pointer Authentication (PAuth) support for ARM     introduced in version 4.0 and fixed in version 5.0.0. A general failure of the signature generation     process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could     obtain the signature of a protected pointer and abuse this flaw to bypass PAuth protection for all     programs running on QEMU. (CVE-2020-10702)

  - hw/display/bochs-display.c in QEMU 4.0.0 does not ensure a sufficient PCI config space allocation, leading     to a buffer overflow involving the PCIe extended config space. (CVE-2019-15034)

  - In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw     occurs in the COPY_AREA macro while handling MMIO write operations through the sm501_2d_engine_write()     callback. A local attacker could abuse this flaw to crash the QEMU process in sm501_2d_operation() in     hw/display/sm501.c on the host, resulting in a denial of service. (CVE-2020-12829)

  - oss_write in audio/ossaudio.c in QEMU before 5.0.0 mishandles a buffer position. (CVE-2020-14415)

  - ati_2d_blt in hw/display/ati_2d.c in QEMU 4.2.1 can encounter an outside-limits situation in a     calculation. A guest can crash the QEMU process. (CVE-2020-27616)

  - ncsi.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of     header data even if that exceeds the total packet length. (CVE-2020-29129)

  - slirp.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of     header data even if that exceeds the total packet length. (CVE-2020-29130)

  - hw/usb/hcd-ohci.c in QEMU 5.0.0 has a stack-based buffer over-read via values obtained from the host     controller driver. (CVE-2020-25624)

  - hw/net/e1000e_core.c in QEMU 5.0.0 has an infinite loop via an RX descriptor with a NULL buffer address.
    (CVE-2020-28916)

  - An out-of-bounds read vulnerability was found in the SLiRP networking implementation of the QEMU emulator.
    This flaw occurs in the icmp6_send_echoreply() routine while replying to an ICMP echo request, also known     as ping. This flaw allows a malicious guest to leak the contents of the host memory, resulting in possible     information disclosure. This flaw affects versions of libslirp before 4.3.1. (CVE-2020-10756)

  - A reachable assertion issue was found in the USB EHCI emulation code of QEMU. It could occur while     processing USB requests due to missing handling of DMA memory map failure. A malicious privileged user     within the guest may abuse this flaw to send bogus USB requests and crash the QEMU process on the host,     resulting in a denial of service. (CVE-2020-25723)

  - A parsing and event loading mismatch in Firefox's SVG code could have allowed load events to fire, even     after sanitization. An attacker already capable of exploiting an XSS vulnerability in privileged internal     pages could have used this attack to bypass our built-in sanitizer. This vulnerability affects Firefox <     83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26951)

  - Firefox did not block execution of scripts with incorrect MIME types when the response was intercepted and     cached through a ServiceWorker. This could lead to a cross-site script inclusion vulnerability, or a     Content Security Policy bypass. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and     Thunderbird < 78.5. (CVE-2020-26958)

  - When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses     as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through     IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding attack.

  - Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. A bug     was discovered in the `flatpak-portal` service that can allow sandboxed applications to execute arbitrary     code on the host system (a sandbox escape). This sandbox-escape bug is present in versions from 0.11.4 and     before fixed versions 1.8.5 and 1.10.0. The Flatpak portal D-Bus service (`flatpak-portal`, also known by     its D-Bus service name `org.freedesktop.portal.Flatpak`) allows apps in a Flatpak sandbox to launch their     own subprocesses in a new sandbox instance, either with the same security settings as the caller or with     more restrictive security settings. For example, this is used in Flatpak-packaged web browsers such as     Chromium to launch subprocesses that will process untrusted web content, and give those subprocesses a     more restrictive sandbox than the browser itself. In vulnerable versions, the Flatpak portal service     passes caller-specified environment variables to non-sandboxed processes on the host system, and in     particular to the `flatpak run` command that is used to launch the new sandbox instance. A malicious or     compromised Flatpak app could set environment variables that are trusted by the `flatpak run` command, and     use them to execute arbitrary code that is not in a sandbox. As a workaround, this vulnerability can be     mitigated by preventing the `flatpak-portal` service from starting, but that mitigation will prevent many     Flatpak apps from working correctly. This is fixed in versions 1.8.5 and 1.10.0. (CVE-2021-21261)

  - The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range     reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when     passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to     sysdeps/ieee754/ldbl-96/e_rem_pio2l.c. (CVE-2020-10029)

  - sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-     based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with     a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to     sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because     of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words,     the reference to 2.23 is intentional despite the mention of Fixed for glibc 2.33 in the 26649 reference.
    (CVE-2020-29573)

  - The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-     byte input sequences in the EUC-KR encoding, may have a buffer over-read. (CVE-2019-25013)

  - An issue was found in Linux kernel before 5.5.4. The mwifiex_cmd_append_vsie_tlv() function in     drivers/net/wireless/marvell/mwifiex/scan.c allows local users to gain privileges or cause a denial of     service because of an incorrect memcpy and buffer overflow, aka CID-b70261a288ea. (CVE-2020-12653)

  - An issue was discovered in Xen through 4.14.x. Some OSes (such as Linux, FreeBSD, and NetBSD) are     processing watch events using a single thread. If the events are received faster than the thread is able     to handle, they will get queued. As the queue is unbounded, a guest may be able to trigger an OOM in the     backend. All systems with a FreeBSD, Linux, or NetBSD (any version) dom0 are vulnerable. (CVE-2020-29568)

  - A flaw was found in the Linux kernels implementation of MIDI, where an attacker with a local account and     the permissions to issue an ioctl commands to midi devices, could trigger a use-after-free. A write to     this specific memory while freed and before use could cause the flow of execution to change and possibly     allow for memory corruption or privilege escalation. (CVE-2020-27786)

  - A locking inconsistency issue was discovered in the tty subsystem of the Linux kernel through 5.9.13.
    drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c may allow a read-after-free attack against TIOCGSID,     aka CID-c8bcd9c5be24. (CVE-2020-29660)

  - mwifiex_cmd_802_11_ad_hoc_start in drivers/net/wireless/marvell/mwifiex/join.c in the Linux kernel through     5.10.4 might allow remote attackers to execute arbitrary code via a long SSID value, aka CID-5c455c5ab332.
