thunderbird: Fix of 255 CVEs

  • rebase from Thunderbird 115.4.1 to 140.12.0 ESR

  • CVE-2022-3032: When receiving an HTML email that contained an iframe element, which used a srcdoc attribute to define the inner HTML document, remote objects specified in the nested document, for example images or videos, were not blocked

  • CVE-2023-0430: Certificate OCSP revocation status was not checked when verifying S/Mime signatures

  • CVE-2023-0547: OCSP revocation status of recipient certificates was not checked when sending S/Mime encrypted email, and revoked certificates would be accepted

  • CVE-2023-0616: If a MIME email combines OpenPGP and OpenPGP MIME data in a certain way Thunderbird repeatedly attempts to process and display the message, which could cause Thunderbird's user interface to lock up and no longer respond to the user's actions

  • CVE-2023-1945: Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially exploitable crash

  • CVE-2023-4573: When receiving rendering data over IPC mStream could have been destroyed when initialized, which could have led to a use-after-free causing a potentially exploitable crash

  • CVE-2023-4574: When creating a callback over IPC for showing the Color Picker window, multiple of the same callbacks could have been created at a time and eventually all simultaneously destroyed as soon as one of the callbacks finished

  • CVE-2023-4575: When creating a callback over IPC for showing the File Picker window, multiple of the same callbacks could have been created at a time and eventually all simultaneously destroyed as soon as one of the callbacks finished

  • CVE-2023-4577: When UpdateRegExpStatics attempted to access initialStringHeap it could already have been garbage collected prior to entering the function, which could potentially have led to an exploitable crash

  • CVE-2023-4578: When calling JS::CheckRegExpSyntax a Syntax Error could have been set which would end in calling convertToRuntimeErrorAndClear. A path in the function could attempt to allocate memory when none is available which would have caused a newly created Out of Memory exception to be mishandled as a Syntax Error

  • CVE-2023-4580: Push notifications stored on disk in private browsing mode were not being encrypted potentially allowing the leak of sensitive information

  • CVE-2023-4581: Excel .xll add-in files did not have a blocklist entry in Firefox's executable blocklist which allowed them to be downloaded without any warning of their potential harm

  • CVE-2023-5169: A compromised content process could have provided malicious data in a PathRecording resulting in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process

  • CVE-2023-5171: During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing an attacker to write two NUL bytes, and cause a potentially exploitable crash

  • CVE-2023-5724: Drivers are not always robust to extremely large draw calls and in some cases this scenario could have led to a crash

  • CVE-2023-5725: A malicious installed WebExtension could open arbitrary URLs, which under the right circumstance could be leveraged to collect sensitive user data

  • CVE-2023-5732: An attacker could have created a malicious link using bidirectional characters to spoof the location in the address bar when visited

  • CVE-2023-6204: On some systems—depending on the graphics settings and drivers—it was possible to force an out-of-bounds read and leak memory data into the images created on the canvas element

  • CVE-2023-6205: It was possible to cause the use of a MessagePort after it had already been freed, which could potentially have led to an exploitable crash

  • CVE-2023-6206: The black fade animation when exiting fullscreen is roughly the length of the anti-clickjacking delay on permission prompts

  • CVE-2023-6207: Ownership…
