  - crossbeam-deque is a package of work-stealing deques for building task schedulers when programming in     Rust. In versions prior to 0.7.4 and 0.8.0, the result of the race condition is that one or more tasks in     the worker queue can be popped twice instead of other tasks that are forgotten and never popped. If tasks     are allocated on the heap, this can cause double free and a memory leak. If not, this still can cause a     logical bug. Crates using `Stealer::steal`, `Stealer::steal_batch`, or `Stealer::steal_batch_and_pop` are     affected by this issue. This has been fixed in crossbeam-deque 0.8.1 and 0.7.4. (CVE-2021-32810)

  - Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. In     versions prior to 1.10.4 and 1.12.0, Flatpak apps with direct access to AF_UNIX sockets such as those used     by Wayland, Pipewire or pipewire-pulse can trick portals and other host-OS services into treating the     Flatpak app as though it was an ordinary, non-sandboxed host-OS process. They can do this by manipulating     the VFS using recent mount-related syscalls that are not blocked by Flatpak's denylist seccomp filter, in     order to substitute a crafted `/.flatpak-info` or make that file disappear entirely. Flatpak apps that act     as clients for AF_UNIX sockets such as those used by Wayland, Pipewire or pipewire-pulse can escalate the     privileges that the corresponding services will believe the Flatpak app has. Note that protocols that     operate entirely over the D-Bus session bus (user bus), system bus or accessibility bus are not affected     by this. This is due to the use of a proxy process `xdg-dbus-proxy`, whose VFS cannot be manipulated by     the Flatpak app, when interacting with these buses. Patches exist for versions 1.10.4 and 1.12.0, and as     of time of publication, a patch for version 1.8.2 is being planned. There are no workarounds aside from     upgrading to a patched version.

  - An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It     permits the visual reordering of characters via control sequences, which can be used to craft source code     that renders different logic than the logical ordering of tokens ingested by compilers and interpreters.
    Adversaries can leverage this to encode source code for compilers accepting Unicode such that targeted     vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium offers the     following alternative approach to presenting this concern. An issue is noted in the nature of     international text that can affect applications that implement support for The Unicode Standard and the     Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-     right and right-to-left characters, the visual order of tokens may be different from their logical order.
    Additionally, control characters needed to fully support the requirements of bidirectional text can     further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such     that the ordering of tokens perceived by human reviewers does not match what will be processed by a     compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its     document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also     provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode     Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the     BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading     visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.

  - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass     RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users     with the ability to start and control a VM to read/write random pages of memory and can result in local     privilege escalation. (CVE-2021-22543)

  - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when     processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested     guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to     enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest     would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak     of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to     5.14-rc7. (CVE-2021-3653)

With `0` width or heigth the     memory allocation will be `0` but the missing bounds checks allow writing to the pointer at this (not     allocated) region. This issue has been patched in FreeRDP 2.4.1. (CVE-2021-41160)

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

The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2021:4116 advisory.

  - The iframe sandbox rules were not correctly applied to XSLT stylesheets, allowing an iframe to bypass     restrictions such as executing scripts or navigating the top-level frame. This vulnerability affects     Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-38503)

  - When interacting with an HTML input element's file picker dialog with webkitdirectory set, a use-after-     free could have resulted, leading to memory corruption and a potentially exploitable crash. This     vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-38504)

  - Through a series of navigations, Firefox could have entered fullscreen mode without notification or     warning to the user. This could lead to spoofing attacks on the browser UI including phishing. This     vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-38506)

  - The Opportunistic Encryption feature of HTTP2 (RFC 8164) allows a connection to be transparently upgraded     to TLS while retaining the visual properties of an HTTP connection, including being same-origin with     unencrypted connections on port 80. However, if a second encrypted port on the same IP address (e.g. port     8443) did not opt-in to opportunistic encryption; a network attacker could forward a connection from the     browser to port 443 to port 8443, causing the browser to treat the content of port 8443 as same-origin     with HTTP. This was resolved by disabling the Opportunistic Encryption feature, which had low usage. This     vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-38507)

  - By displaying a form validity message in the correct location at the same time as a permission prompt     (such as for geolocation), the validity message could have obscured the prompt, resulting in the user     potentially being tricked into granting the permission. This vulnerability affects Firefox < 94,     Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-38508)

  - Due to an unusual sequence of attacker-controlled events, a Javascript alert() dialog with arbitrary     (although unstyled) contents could be displayed over top an uncontrolled webpage of the attacker's     choosing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
    (CVE-2021-38509)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 93 and Firefox ESR     91.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some     of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 94,     Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-43534)

  - A use-after-free could have occured when an HTTP2 session object was released on a different thread,     leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 93,     Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-43535)

    (CVE-2021-38509)

  - Thunderbird versions prior to 91.3.0 are vulnerable to the heap overflow described in CVE-2021-43527 when     processing S/MIME messages. Thunderbird versions 91.3.0 and later will not call the vulnerable code when     processing S/MIME messages that contain certificates with DER-encoded DSA or RSA-PSS signatures.
