Quote:Mozilla has released a new update for Thunderbird email client on the supported desktop platforms, namely Windows, Linux, and macOS.
 
Thunderbird continues to be one of the top email clients on all these operating systems, despite the majority of updates shipped by Mozilla bringing nothing else than bug fixes and small refinements here and there.
 
This is also the case of Thunderbird 60.7.1, which includes just two different improvements, comes with a fix for a bug removing the prompt for smartcard PIN when S/MIME signing was used.
 
The heap and buffer overflow bugs can lead to a potentially exploitable crash, whereas the type confusion issue can only close the app with no further possible damage. The first three CVEs mentioned above have received a high severity rating, while the fourth has a low impact.
 
There are two issues in this release, but both of them exist in the previous builds too. First of all, the Twitter module no longer works because of API changes on the service, and second of all, profiles stored on Windows network shares are accessible via UNC not with drive letter.
