The version of Firefox ESR installed on the remote Windows host is prior to 115.29. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-82 advisory.

  - Memory safety bugs present in Firefox ESR 115.28, Firefox ESR 140.3, Thunderbird ESR 140.3, Firefox 143     and Thunderbird 143. 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-2025-11714)

  - A compromised web process using malicious IPC messages could have caused the privileged browser process to     reveal blocks of its memory to the compromised process. (CVE-2025-11710)

  - A compromised web process was able to trigger out of bounds reads and writes in a more privileged process     using manipulated WebGL textures. (CVE-2025-11709)

  - There was a way to change the value of JavaScript Object properties that were supposed to be non-     writeable. (CVE-2025-11711)

The AlmaLinux 9.2 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1785560172 advisory.

  - 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)

  - If a MIME email combines OpenPGP and OpenPGP MIME data in a certain way Thunderbird repeatedly attempts to     process and display the message, which could cause Thunderbird's user interface to lock up and no longer     respond to the user's actions. An attacker could send a crafted message with this structure to attempt a     DoS attack. This vulnerability affects Thunderbird < 102.8. (CVE-2023-0616)

  - Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially     exploitable crash. This vulnerability affects Thunderbird < 102.10 and Firefox ESR < 102.10.
    (CVE-2023-1945)

  - 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`. This vulnerability affects Firefox < 109, Firefox ESR < 102.7, and Thunderbird <     102.7. (CVE-2023-23598)

  - When importing a SPKI RSA public key as ECDSA P-256, the key would be handled incorrectly causing the tab     to crash. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.
