    Multiple security issues were discovered in Thunderbird, which could     result in the execution of arbitrary code or information disclosure

    For the stable distribution (bookworm), these problems have been fixed in     version 1:128.10.0esr-1~deb12u1.

    We recommend that you upgrade your thunderbird packages.

    For the detailed security status of thunderbird please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/thunderbird

The version of Thunderbird ESR installed on the remote macOS or Mac OS X host is prior to 128.10. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-32 advisory.

  - Memory safety bugs present in Firefox 137, Thunderbird 137, Firefox ESR 128.9, and Thunderbird 128.9. 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-2025-4091)

  - Thunderbird's update mechanism allowed a medium-integrity user process to interfere with the SYSTEM-level     updater by manipulating the file-locking behavior. By injecting code into the user-privileged process, an     attacker could bypass intended access controls, allowing SYSTEM-level file operations on paths controlled     by a non-privileged user and enabling privilege escalation. (CVE-2025-2817)

  - Modification of specific WebGL shader attributes could trigger an out-of-bounds read, which, when chained     with other vulnerabilities, could be used to escalate privileges. This bug only affects Thunderbird for     macOS. Other versions of Thunderbird are unaffected. (CVE-2025-4082)

  - A process isolation vulnerability in Thunderbird stemmed from improper handling of javascript: URIs, which     could allow content to execute in the top-level document's process instead of the intended frame,     potentially enabling a sandbox escape. (CVE-2025-4083)

  - Due to insufficient escaping of the special characters in the copy as cURL feature, an attacker could     trick a user into using this command, potentially leading to local code execution on the user's system.
    This bug only affects Firefox for Windows. Other versions of Firefox are unaffected. (CVE-2025-4084)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Thunderbird installed on the remote Windows host is prior to 138.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-31 advisory.

  - Memory safety bugs present in Firefox 137, Thunderbird 137, Firefox ESR 128.9, and Thunderbird 128.9. 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-2025-4091)

  - An attacker with control over a content process could potentially leverage the privileged UITour actor to     leak sensitive information or escalate privileges. (CVE-2025-4085)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 128.10. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-29 advisory.

    A process isolation vulnerability in Firefox stemmed from improper handling of javascript: URIs, which     could allow content to execute in the top-level document's process instead of the intended frame,     potentially enabling a sandbox escape. This vulnerability affects Firefox < 138, Firefox ESR < 128.10,     Firefox ESR < 115.23, Thunderbird < 138, and Thunderbird ESR < 128.10. (CVE-2025-4083)
