Signatures are written to disk before and read during verification, which might be subject to a race condition when a malicious local process or user is replacing the file. This vulnerability affects Thunderbird < 78.10.

The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2021:1350 advisory.

  - Further techniques that built on the slipstream research combined with a malicious webpage could have     exposed both an internal network's hosts as well as services running on the user's local machine. This     vulnerability affects Firefox < 85. (CVE-2021-23961)

  - A WebGL framebuffer was not initialized early enough, resulting in memory corruption and an out of bound     write. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88.
    (CVE-2021-23994)

  - When Responsive Design Mode was enabled, it used references to objects that were previously freed. We     presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability     affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. (CVE-2021-23995)

  - Through complicated navigations with new windows, an HTTP page could have inherited a secure lock icon     from an HTTPS page. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88.
    (CVE-2021-23998)

  - If a Blob URL was loaded through some unusual user interaction, it could have been loaded by the System     Principal and granted additional privileges that should not be granted to web content. This vulnerability     affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. (CVE-2021-23999)

  - When a user clicked on an FTP URL containing encoded newline characters (%0A and %0D), the newlines would     have been interpreted as such and allowed arbitrary commands to be sent to the FTP server. This     vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. (CVE-2021-24002)

  - The WebAssembly JIT could miscalculate the size of a return type, which could lead to a null read and     result in a crash. *Note: This issue only affected x86-32 platforms. Other platforms are unaffected.*.
    This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. (CVE-2021-29945)

  - Ports that were written as an integer overflow above the bounds of a 16-bit integer could have bypassed     port blocking restrictions when used in the Alt-Svc header. This vulnerability affects Firefox ESR <     78.10, Thunderbird < 78.10, and Firefox < 88. (CVE-2021-29946)

  - Signatures are written to disk before and read during verification, which might be subject to a race     condition when a malicious local process or user is replacing the file. This vulnerability affects     Thunderbird < 78.10. (CVE-2021-29948)

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4995-1 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 security restrictions, or execute arbitrary     code. (CVE-2021-23961, CVE-2021-23981, CVE-2021-23982, CVE-2021-23987, CVE-2021-23994, CVE-2021-23998,     CVE-2021-23999, CVE-2021-29945, CVE-2021-29946, CVE-2021-29967)

    It was discovered that extensions could open popup windows with control of the window title in some     circumstances. If a user were tricked into installing a specially crafted extension, an attacker could     potentially exploit this to spoof a website and trick the user into providing credentials.
    (CVE-2021-23984)

    Multiple security issues were discovered in Thunderbird's OpenPGP integration. If a user were tricked into     importing a specially crafted key in some circumstances, an attacker could potentially exploit this to     cause a denial of service (inability to send encrypted email) or confuse the user. (CVE-2021-23991,     CVE-2021-23992, CVE-2021-23993)

    A use-after-free was discovered when Responsive Design Mode was enabled. If a user were tricked into     opening a specially crafted website with Responsive Design Mode enabled, an attacker could potentially     exploit this to cause a denial of service, or execute arbitrary code. (CVE-2021-23995)

    It was discovered that Thunderbird mishandled ftp URLs with encoded newline characters. If a user were     tricked into clicking on a specially crafted link, an attacker could potentially exploit this to send     arbitrary FTP commands. (CVE-2021-24002)

    It was discovered that Thunderbird wrote signatures to disk and read them back during verification. A     local attacker could potentially exploit this to replace the data with another signature file.
    (CVE-2021-29948)

    It was discovered that Thunderbird might load an alternative OTR library. If a user were tricked into     copying a specially crafted library to one of Thunderbird's search paths, an attacker could potentially     exploit this to execute arbitrary code. (CVE-2021-29949)

    It was discovered that secret keys imported into Thunderbird were stored unencrypted. A local attacker     could potentially exploit this to obtain private keys. (CVE-2021-29956)

    It was discovered that Thunderbird did not indicate when an inline signed or encrypted message contained     additional unprotected parts. (CVE-2021-29957)

The version of Thunderbird installed on the remote Windows host is prior to 78.10. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2021-14 advisory.

  - A WebGL framebuffer was not initialized early enough, resulting in memory corruption and an out of bound     write. (CVE-2021-23994)

  - When Responsive Design Mode was enabled, it used references to objects that were previously freed. We     presume that with enough effort this could have been exploited to run arbitrary code. (CVE-2021-23995)

  - Through complicated navigations with new windows, an HTTP page could have inherited a secure lock icon     from an HTTPS page. (CVE-2021-23998)

  - Further techniques that built on the slipstream research combined with a malicious webpage could have     exposed both an internal network's hosts as well as services running on the user's local machine.
    (CVE-2021-23961)

  - If a Blob URL was loaded through some unusual user interaction, it could have been loaded by the System     Principal and granted additional privileges that should not be granted to web content. (CVE-2021-23999)

  - When a user clicked on an FTP URL containing encoded newline characters (%0A and %0D), the newlines would     have been interpreted as such and allowed arbitrary commands to be sent to the FTP server.
    (CVE-2021-24002)

  - The WebAssembly JIT could miscalculate the size of a return type, which could lead to a null read and     result in a crash. Note: This issue only affected x86-32 platforms. Other platforms are unaffected.
    (CVE-2021-29945)

  - Ports that were written as an integer overflow above the bounds of a 16-bit integer could have bypassed     port blocking restrictions when used in the Alt-Svc header. (CVE-2021-29946)

  - Signatures are written to disk before and read during verification, which might be subject to a race     condition when a malicious local process or user is replacing the file. (CVE-2021-29948)
