The version of thunderbird installed on the remote host is prior to 91.6.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1818 advisory.

    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)

    During operations on MessageTasks, a task may have been removed while it was still scheduled, resulting in     memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.15,     Thunderbird < 91.2, Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38496)

    Through use of reportValidity() and window.open(), a plain-text validation message could have been     overlaid on another origin, leading to possible user confusion and spoofing attacks. This vulnerability     affects Firefox < 93, Thunderbird < 91.2, and Firefox ESR < 91.2. (CVE-2021-38497)

    During process shutdown, a document could have caused a use-after-free of a languages service object,     leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 93,     Thunderbird < 91.2, and Firefox ESR < 91.2. (CVE-2021-38498)

    Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1. 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 Thunderbird < 78.15, Thunderbird < 91.2,     Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38500)

    Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1. 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 < 93, Thunderbird < 91.2, and     Firefox ESR < 91.2. (CVE-2021-38501)

    Thunderbird ignored the configuration to require STARTTLS security for an SMTP connection. A MITM could     perform a downgrade attack to intercept transmitted messages, or could take control of the authenticated     session to execute SMTP commands chosen by the MITM. If an unprotected authentication method was     configured, the MITM could obtain the authentication credentials, too. This vulnerability affects     Thunderbird < 91.2. (CVE-2021-38502)

    The Mozilla Foundation Security Advisory describes this flaw as:

    It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox.
    (CVE-2021-4140)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Constructing audio sinks could have lead to a race condition when playing audio files and closing windows.
    This could have lead to a use-after-free causing a potentially exploitable crash. (CVE-2022-22737)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Applying a CSS filter effect could have accessed out of bounds memory. This could have lead to a heap-     buffer-overflow causing a potentially exploitable crash. (CVE-2022-22738)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Malicious websites could have tricked users into accepting launching a program to handle an external URL     protocol. (CVE-2022-22739)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Certain network request objects were freed too early when releasing a network request handle. This could     have lead to a use-after-free causing a potentially exploitable crash. (CVE-2022-22740)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When resizing a popup while requesting fullscreen access, the popup would have become unable to leave     fullscreen mode. (CVE-2022-22741)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When inserting text while in edit mode, some characters might have lead to out-of-bounds memory access     causing a potentially exploitable crash. (CVE-2022-22742)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When navigating from inside an iframe while requesting fullscreen access, an attacker-controlled tab could     have made the browser unable to leave fullscreen mode. (CVE-2022-22743)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Securitypolicyviolation events could have leaked cross-origin information for frame-ancestors violations     (CVE-2022-22745)

    The Mozilla Foundation Security Advisory describes this flaw as:

    After accepting an untrusted certificate, handling an empty pkcs7 sequence as part of the certificate data     could have lead to a crash. This crash is believed to be unexploitable. (CVE-2022-22747)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Malicious websites could have confused Thunderbird into showing the wrong origin when asking to launch a     program and handling an external URL protocol. (CVE-2022-22748)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Mozilla developers Calixte Denizet, Kershaw Chang, Christian Holler, Jason Kratzer, Gabriele Svelto, Tyson     Smith, Simon Giesecke, and Steve Fink reported memory safety bugs present in Firefox 95 and Firefox ESR     91.4. 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. (CVE-2022-22751)

    The Mozilla Foundation Security Advisory describes this flaw as:

    If a user installed an extension of a particular type, the extension could have auto-updated itself and     while doing so, bypass the prompt which grants the new version the new requested permissions.
    (CVE-2022-22754)

    The Mozilla Foundation Security Advisory describes this flaw as:

    If a user was convinced to drag and drop an image to their desktop or other folder, the resulting object     could have been changed into an executable script which would have run arbitrary code after the user     clicked on it. (CVE-2022-22756)

    The Mozilla Foundation Security Advisory describes this flaw as:

    If a document created a sandboxed iframe without allow-scripts, and subsequently appended an element to     the iframe's document that e.g. had a JavaScript event handler - the event handler would have run despite     the iframe's sandbox. (CVE-2022-22759)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When importing resources using Web Workers, error messages would distinguish the difference between     application/javascript responses and non-script responses. This could have been abused to learn     information cross-origin. (CVE-2022-22760)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Web-accessible extension pages (pages with a moz-extension:// scheme) were not correctly enforcing the     frame-ancestors directive when it was used in the Web Extension\'s Content Security Policy.
    (CVE-2022-22761)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When a worker is shutdown, it was possible to cause script to run late in the lifecycle, at a point after     where it should not be possible. (CVE-2022-22763)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Mozilla developers and community members Paul Adenot and the Mozilla Fuzzing Team reported memory safety     bugs present in Firefox 96 and Firefox ESR 91.5. 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.
    (CVE-2022-22764)

    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)

    A flaw was found in Thunderbird, which is 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.
    (CVE-2021-43529)

    References to CVE-2021-38503 and CVE-2021-43529 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 2022-07-06.

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

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