The version of Thunderbird installed on the remote Windows host is prior to 128.7. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-10 advisory.

  - Memory safety bugs present in Firefox 134, Thunderbird 134, Firefox ESR 128.6, and Thunderbird 128.6. 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-2025-1017)

  - An attacker could have caused a use-after-free via crafted XSLT data, leading to a potentially exploitable     crash. (CVE-2025-1009)

  - An attacker could have caused a use-after-free via the Custom Highlight API, leading to a potentially     exploitable crash. (CVE-2025-1010)

  - A bug in WebAssembly code generation could have lead to a crash. It may have been possible for an attacker     to leverage this to achieve code execution. (CVE-2025-1011)

  - A race during concurrent delazification could have led to a use-after-free. (CVE-2025-1012)
