[German]The developers of the e-mail client Thunderbird have released version 68.6.0 on 12.3.2020. This is a maintenance update (no security fixes) for the 68 main version of the email client.
German blog reader Ralf noticed within this comment the Thunderbird update (thanks). On my system the new version has been offered. During a quick check, the update installed without any issues.
New features and bug fixes
According to the release notes the new Thunderbird shows a popup at startup with a new profile. In addition, the Thunderbird now offers partial updates, which lead to smaller downloads. In the new version of Thunderbird the following bug fixes have been made:
- Searching in message bodies led to false negatives under some circumstances in quoted-printable encoded HTML bodies
- "Get New Messages for All Accounts" not working for OAuth2-authenticated IMAP accounts
If you experience problems with Lightning (calendar add-on) after upgrading from version 60 to the current version, this support article should help.
The readme also states that there have been security fixes. These are listed on this page.
- CVE-2020-6805: Use-after-free when removing data about origins: When removing data about an origin whose tab was recently closed, a use-after-free could occur in the Quota manager, resulting in a potentially exploitable crash
- CVE-2020-6806: BodyStream::OnInputStreamReady was missing protections against state confusion: By carefully crafting promise resolutions, it was possible to cause an out-of-bounds read off the end of an array resized during script execution. This could have led to memory corruption and a potentially exploitable crash.
- CVE-2020-6807: Use-after-free in cubeb during stream destruction: When a device was changed while a stream was about to be destroyed, the
stream-reinittask may have been executed after the stream was destroyed, causing a use-after-free and a potentially exploitable crash.
- CVE-2020-6811: Devtools' 'Copy as cURL' feature did not fully escape website-controlled data, potentially leading to command injection: The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request, which can be controlled by the website. If a user used the 'Copy as Curl' feature and pasted the command into a terminal, it could have resulted in command injection and arbitrary command execution.
- CVE-2019-20503: Out of bounds reads in sctp_load_addresses_from_init: The inputs to
sctp_load_addresses_from_initare verified by
sctp_arethere_unrecognized_parameters; however, the two functions handled parameter bounds differently, resulting in out of bounds reads when parameters are partially outside a chunk.
- CVE-2020-6812: The names of AirPods with personally identifiable information were exposed to websites with camera or microphone permission: The first time AirPods are connected to an iPhone, they become named after the user's name by default (e.g. Jane Doe's AirPods.) Websites with camera or microphone permission are able to enumerate device names, disclosing the user's name. To resolve this issue, Firefox added a special case that renames devices containing the substring 'AirPods' to simply 'AirPods'.
- CVE-2020-6814: Memory safety bugs fixed in Thunderbird 68.6: Mozilla developers Byron Campen, Jason Kratzer, and Christian Holler reported memory safety bugs present in Thunderbird 68.5. 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.
Several fixes are rated 'high', while other fixes are rated moderate. Details can be found on this page if required.
The system requirements for the different operating system versions (see also):
- Windows: Windows 7, Windows Server 2008 R2 or higher
