CVE ID : CVE-2022-40956 CVE-2022-40957 CVE-2022-40958 CVE-2022-40959

Multiple security issues were discovered in Thunderbird, which could
result in denial of service or the execution of arbitrary code.

Debian follows the Thunderbird upstream releases. Support for the 91.x
series has ended, so starting with this update we're now following the
102.x series.

For Debian 10 buster, these problems have been fixed in version
1:102.3.0-1~deb10u1.

We recommend that you upgrade your thunderbird packages.
