The version of Thunderbird installed on the remote Windows host is prior to 156.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2026-94 advisory.

  - A maliciously constructed mail header could lead to multiple fields being parsed as one, or potential     memory safety violations. (CVE-2026-92238)

  - A maliciously constructed IMAP line could cause an out-of-bounds buffer read. (CVE-2026-92239)

  - A malicious or compromised IMAP server can trigger an out-of-bounds read in the IMAP response parser by     sending an untagged ' ID' response, crashing Thunderbird. The affected parsing path is reachable before     authentication. (CVE-2026-92240)

  - Use-after-free in the Audio/Video: Web Codecs component. This vulnerability was fixed in Firefox 156,     Firefox ESR 140.16, Firefox ESR 153.3, Thunderbird 156, Thunderbird 140.16, and Thunderbird 153.3.
