The version of Firefox installed on the remote Windows host is prior to 98.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-10 advisory.

  - If an attacker could control the contents of an iframe sandboxed with <code>allow-popups</code> but not     <code>allow-scripts</code>, they were able to craft a link that, when clicked, would lead to JavaScript     execution in violation of the sandbox. (CVE-2022-26384)

  - When resizing a popup after requesting fullscreen access, the popup would not display the fullscreen     notification. (CVE-2022-26383)

  - When installing an add-on, Firefox verified the signature before prompting the user; but while the user     was confirming the prompt, the underlying add-on file could have been modified and Firefox would not have     noticed. (CVE-2022-26387)

  - An attacker could have caused a use-after-free by forcing a text reflow in an SVG object leading to a     potentially exploitable crash. (CVE-2022-26381)

  - While the text displayed in Autofill tooltips cannot be directly read by JavaScript, the text was rendered     using page fonts. Side-channel attacks on the text by using specially crafted fonts could have lead to     this text being inferred by the webpage. (CVE-2022-26382)

The version of thunderbird installed on the remote host is prior to 91.7.0-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1779 advisory.

    A flaw was found in Thunderbird. The vulnerability occurs due to an out-of-bounds write of one byte when     processing the message. This flaw allows an attacker to craft an email message that causes Thunderbird to     perform an out-of-bounds write. (CVE-2022-0566)

    A flaw was found in expat. Passing malformed 2- and 3-byte UTF-8 sequences (for example, from start tag     names) to the XML processing application on top of expat can lead to arbitrary code execution. This issue     is dependent on how invalid UTF-8 is handled inside the XML processor. (CVE-2022-25235)

    A flaw was found in expat. Passing one or more namespace separator characters in the xmlns[:prefix]     attribute values made expat send malformed tag names to the XML processor on top of expat. This issue     causes arbitrary code execution depending on how unexpected cases are handled inside the XML processor.
    (CVE-2022-25236)

    An integer overflow was found in expat. The issue occurs in storeRawNames() by abusing the m_buffer     expansion logic to allow allocations very close to INT_MAX and out-of-bounds heap writes. This flaw can     cause a denial of service or potentially arbitrary code execution. (CVE-2022-25315)

    The Mozilla Foundation Security Advisory describes this flaw as:

    An attacker could have caused a use-after-free by forcing a text reflow in an SVG object leading to a     potentially exploitable crash. (CVE-2022-26381)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When resizing a popup after requesting fullscreen access, the popup would not display the fullscreen     notification. (CVE-2022-26383)

    The Mozilla Foundation Security Advisory describes this flaw as:

    If an attacker could control the contents of an iframe sandboxed with allow-popups but not allow-scripts,     they were able to craft a link that, when clicked, would lead to JavaScript execution in violation of the     sandbox. (CVE-2022-26384)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Previously Thunderbird for macOS and Linux would download temporary files to a user-specific directory in     /tmp, but this behavior was changed to download them to /tmp where they could be affected by other local     users. This behavior was reverted to the original, user-specific directory. (CVE-2022-26386)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When installing an add-on, Thunderbird verified the signature before prompting the user; but while the     user was confirming the prompt, the underlying add-on file could have been modified and Thunderbird would     not have noticed. (CVE-2022-26387)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Removing an XSLT parameter during processing could have lead to an exploitable use-after-free. We have had     reports of attacks in the wild abusing this flaw. (CVE-2022-26485)

    The Mozilla Foundation Security Advisory describes this flaw as:

    An unexpected message in the WebGPU IPC framework could lead to a use-after-free and exploitable sandbox     escape. We have had reports of attacks in the wild abusing this flaw. (CVE-2022-26486)
