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.

 - An out of date graphics library (Angle) likely contained vulnerabilities that could potentially be exploited.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)

 - If an object prototype was corrupted by an attacker, they would have been able to set undesired attributes on a JavaScript object, leading to privileged code execution. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (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)

 - If there was a PAC URL set and the server that hosts the PAC was not reachable, OCSP requests would have been blocked, resulting in incorrect error pages being shown. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34472)

 - A malicious website that could create a popup could have resized the popup to overlay the address bar with its own content, resulting in potential user confusion or spoofing attacks. *This bug only affects Thunderbird for Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34479)

 - In the <code>nsTArray_Impl::ReplaceElementsAt()</code> function, an integer overflow could have occurred when the number of elements to replace was too large for the container. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (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)

 - During startup, a graphics driver with an unexpected name could lead to a stack-buffer overflow causing a potentially exploitable crash. *This issue only affects Firefox for Android. Other operating systems are not affected.*. This vulnerability affects Firefox < 105. (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)

 - An out of date library (libusrsctp) contained vulnerabilities that could potentially be exploited. This vulnerability affects Firefox < 108. (CVE-2022-46871)

 - 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 Thunderbird for Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 108, Firefox ESR < 102.6, and Thunderbird < 102.6. (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. *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. *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)

 - An optimization in WebGL was incorrect in some cases, and could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 106, Firefox ESR < 102.6, and Thunderbird < 102.6. (CVE-2022-46881)

 - A use-after-free in WebGL extensions could have led to a potentially exploitable crash. This vulnerability affects Firefox < 107, Firefox ESR < 102.6, and Thunderbird < 102.6. (CVE-2022-46882)

 - Mozilla: Arbitrary file read from GTK drag and drop on Linux (CVE-2023-23598)

 - Mozilla: Malicious command could be hidden in devtools output (CVE-2023-23599)

 - Mozilla: URL being dragged from cross-origin iframe into same tab triggers navigation (CVE-2023-23601)

 - Mozilla: Content Security Policy wasn't being correctly applied to WebSockets in WebWorkers (CVE-2023-23602)

 - Mozilla: Calls to <code>console.log</code> allowed bypasing Content Security Policy via format directive (CVE-2023-23603)
