The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2022:4891 advisory.

  - When displaying the sender of an email, and the sender name contained the Braille Pattern Blank space     character multiple times, Thunderbird would have displayed all the spaces. This could have been used by an     attacker to send an email message with the attacker's digital signature, that was shown with an arbitrary     sender email address chosen by the attacker. If the sender name started with a false email address,     followed by many Braille space characters, the attacker's email address was not visible. Because     Thunderbird compared the invisible sender address with the signature's email address, if the signing key     or certificate was accepted by Thunderbird, the email was shown as having a valid digital signature. This     vulnerability affects Thunderbird < 91.10. (CVE-2022-1834)

  - A malicious website could have learned the size of a cross-origin resource that supported Range requests.
    This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. (CVE-2022-31736)

  - A malicious webpage could have caused an out-of-bounds write in WebGL, leading to memory corruption and a     potentially exploitable crash. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox     ESR < 91.10. (CVE-2022-31737)

  - When exiting fullscreen mode, an iframe could have confused the browser about the current state of     fullscreen, resulting in potential user confusion or spoofing attacks. This vulnerability affects     Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. (CVE-2022-31738)

  - On arm64, WASM code could have resulted in incorrect assembly generation leading to a register allocation     problem, and a potentially exploitable crash. This vulnerability affects Thunderbird < 91.10, Firefox <     101, and Firefox ESR < 91.10. (CVE-2022-31740)

  - A crafted CMS message could have been processed incorrectly, leading to an invalid memory read, and     potentially further memory corruption. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and     Firefox ESR < 91.10. (CVE-2022-31741)

  - An attacker could have exploited a timing attack by sending a large number of allowCredential entries and     detecting the difference between invalid key handles and cross-origin key handles. This could have led to     cross-origin account linking in violation of WebAuthn goals. This vulnerability affects Thunderbird <     91.10, Firefox < 101, and Firefox ESR < 91.10. (CVE-2022-31742)

  - Mozilla developers Andrew McCreight, Nicolas B. Pierron, and the Mozilla Fuzzing Team reported memory     safety bugs present in Firefox 100 and Firefox ESR 91.9. 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. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
    (CVE-2022-31747)

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5512-1 advisory.

    Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially     crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of     service, obtain sensitive information, spoof the UI, bypass CSP restrictions, or execute arbitrary code.
    (CVE-2022-2200, CVE-2022-31736, CVE-2022-31737, CVE-2022-31738, CVE-2022-31740, CVE-2022-31741,     CVE-2022-31742, CVE-2022-31744, CVE-2022-31747, CVE-2022-34468, CVE-2022-34470, CVE-2022-34479,     CVE-2022-34481, CVE-2022-34484)

    It was discovered that an unavailable PAC file caused OCSP requests to be blocked, resulting in incorrect     error pages being displayed. (CVE-2022-34472)

    It was discovered that the Braille space character could be used to cause Thunderbird to display the wrong     sender address for signed messages. An attacker could potentially exploit this to trick the user into     believing a message had been sent from somebody they trusted. (CVE-2022-1834)

    It was discovered that Thunderbird would consider an email with a mismatched OpenPGP signature date as     valid. An attacker could potentially exploit this by replaying an older message in order to trick the user     into believing that the statements in the message are current. (CVE-2022-2226)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - On arm64, WASM code could have resulted in incorrect assembly generation leading to a register allocation     problem, and a potentially exploitable crash. This vulnerability affects Thunderbird < 91.10, Firefox <     101, and Firefox ESR < 91.10. (CVE-2022-31740)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote NewStart CGSL host, running version MAIN 6.02, has firefox packages installed that are affected by multiple vulnerabilities:

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox. This     vulnerability affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5. (CVE-2021-4140)

  - crossbeam-deque is a package of work-stealing deques for building task schedulers when programming in     Rust. In versions prior to 0.7.4 and 0.8.0, the result of the race condition is that one or more tasks in     the worker queue can be popped twice instead of other tasks that are forgotten and never popped. If tasks     are allocated on the heap, this can cause double free and a memory leak. If not, this still can cause a     logical bug. Crates using `Stealer::steal`, `Stealer::steal_batch`, or `Stealer::steal_batch_and_pop` are     affected by this issue. This has been fixed in crossbeam-deque 0.8.1 and 0.7.4. (CVE-2021-32810)

  - Mozilla developers reported memory safety bugs present in Firefox 91 and Firefox ESR 78.13. 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 ESR < 78.14, Thunderbird < 78.14,     and Firefox < 92. (CVE-2021-38493)

  - During operations on MessageTasks, a task may have been removed while it was still scheduled, resulting in     memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.15,     Thunderbird < 91.2, Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38496)
