An out of date graphics library (Angle) likely contained vulnerabilities that could potentially be exploited. This vulnerability affects Thunderbird < 78.9 and Firefox ESR < 78.9.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The version of thunderbird installed on the remote host is prior to 102.7.1-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1951 advisory.

    2024-05-23: CVE-2023-0430 was added to this advisory.

    An out of date graphics library (Angle) likely contained vulnerabilities that could potentially be     exploited. This vulnerability affects Thunderbird < 78.9 and Firefox ESR < 78.9. (CVE-2021-4127)

    Mozilla developers and community members Julian Hector, Randell Jesup, Gabriele Svelto, Tyson Smith,     Christian Holler, and Masayuki Nakano reported memory safety bugs present in Firefox 94. 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 < 95, Firefox ESR < 91.4.0, and     Thunderbird < 91.4.0. (CVE-2021-4129)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of if an     attacker corrupted an object prototype, they could set undesired attributes on a JavaScript object,     leading to privileged code execution. (CVE-2022-2200)

    An out-of-bounds read can occur when decoding H264 video. This results in a potentially exploitable crash.
    This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105. (CVE-2022-3266)

    An iframe that was not permitted to run scripts could do so if the user clicked on a     <code>javascript:</code> link. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird     < 102, and Thunderbird < 91.11. (CVE-2022-34468)

    Session history navigations may have led to a use-after-free and potentially exploitable crash. This     vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11.
    (CVE-2022-34470)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue that if a PAC     URL was set and the server that hosts the PAC was not reachable, OCSP requests are blocked, resulting in     incorrect error pages being shown. (CVE-2022-34472)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of a malicious     website that creates a popup that could have resized the popup to overlay the address bar with its own     content, resulting in potential user confusion or spoofing attacks. (CVE-2022-34479)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue within the     `nsTArray_Impl::ReplaceElementsAt()` function, where an integer overflow could occur when the number of     elements to replace was too large for the container. (CVE-2022-34481)

    The Mozilla Fuzzing Team reported potential vulnerabilities present in Thunderbird 91.10. 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 < 102, Firefox ESR < 91.11,     Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34484)

    A stack based buffer overflow vulnerability was identified in Mozilla Firefox and Firefox ESR. This     vulnerability occurs when the buffer being overwritten is allocated on the stack (i.e., is a local     variable or, rarely, a parameter to a function). An attacker could cause of denial-of-service style crash     by exploiting this vulnerability. To exploit this vulnerability, a remote, unauthenticated attacker would     need to convince a user to visit a specially crafted website or open a malicious document.
    (CVE-2022-40961)

    If a Thunderbird user quoted from an HTML email, for example by replying to the email, and the email     contained either a VIDEO tag with the POSTER attribute or an OBJECT tag with a DATA attribute, a network     request to the referenced remote URL was performed, regardless of a configuration to block remote content.
    An image loaded from the POSTER attribute was shown in the composer window. These issues could have given     an attacker additional capabilities when targetting releases that did not yet have a fix for CVE-2022-3033     which was reported around three months ago. This vulnerability affects Thunderbird < 102.5.1.
    (CVE-2022-45414)

    RESERVEDNOTE: https://www.mozilla.org/en-US/security/advisories/mfsa2022-51/#CVE-2022-46871     (CVE-2022-46871)

    The Mozilla Foundation Security Advisory describes this flaw as: An attacker who compromised a content     process could have partially escaped the sandbox to read arbitrary files via clipboard-related IPC     messages.

    *This bug only affects Firefox for Linux. Other operating systems are unaffected.* (CVE-2022-46872)

    A file with a long filename could have had its filename truncated to remove the valid extension, leaving a     malicious extension in its place. This could potentially led to user confusion and the execution of     malicious code.<br/>*Note*: This issue was originally included in the advisories for Thunderbird 102.6,     but a patch (specific to Thunderbird) was omitted, resulting in it actually being fixed in Thunderbird     102.6.1. This vulnerability affects Firefox < 108, Thunderbird < 102.6.1, Thunderbird < 102.6, and Firefox     ESR < 102.6. (CVE-2022-46874)

    By confusing the browser, the fullscreen notification could have been delayed or suppressed, resulting in     potential user confusion or spoofing attacks. This vulnerability affects Firefox < 108. (CVE-2022-46877)

    Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the Mozilla Fuzzing Team reported memory     safety bugs present in Thunderbird 102.5. 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. This     vulnerability affects Firefox < 108, Firefox ESR < 102.6, and Thunderbird < 102.6. (CVE-2022-46878)

    A missing check related to tex units could have led to a use-after-free and potentially exploitable     crash.<br />*Note*: This advisory was added on December 13th, 2022 after we better understood the impact     of the issue. The fix was included in the original release of Firefox 105. This vulnerability affects     Firefox ESR < 102.6, Firefox < 105, and Thunderbird < 102.6. (CVE-2022-46880)

    The Mozilla Foundation Security Advisory describes this flaw as: An optimization in WebGL was incorrect in     some cases, and could have led to memory corruption and a potentially exploitable crash. (CVE-2022-46881)

    The Mozilla Foundation Security Advisory describes this flaw as: A use-after-free in WebGL extensions     could have led to a potentially exploitable crash. (CVE-2022-46882)

    Certificate OCSP revocation status was not checked when verifying S/Mime signatures. Mail signed with a     revoked certificate would be displayed as having a valid signature. Thunderbird versions from 68 to     102.7.0 were affected by this bug. This vulnerability affects Thunderbird < 102.7.1. (CVE-2023-0430)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Due to the Firefox GTK wrapper code's use of text/plain for drag data and GTK treating all text/plain     MIMEs containing file URLs as being dragged a website could arbitrarily read a file via a call to     DataTransfer.setData. (CVE-2023-23598)

    The Mozilla Foundation Security Advisory describes this flaw as:

    When copying a network request from the developer tools panel as a curl command the output was not being     properly sanitized and could allow arbitrary commands to be hidden within. (CVE-2023-23599)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Navigations were being allowed when dragging a URL from a cross-origin iframe into the same tab which     could lead to website spoofing attacks (CVE-2023-23601)

    The Mozilla Foundation Security Advisory describes this flaw as:

    A mishandled security check when creating a WebSocket in a WebWorker caused the Content Security Policy     connect-src header to be ignored. This could lead to connections to restricted origins from inside     WebWorkers. (CVE-2023-23602)

    Regular expressions used to filter out forbidden properties and values from style directives in calls to     console.log weren't accounting for external URLs. Data could then be potentially exfiltrated from the     browser. (CVE-2023-23603)

    The Mozilla Foundation Security Advisory describes this flaw as:

    Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108 and     Firefox ESR 102.6. 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-2023-23605)
