Multiple security issues were discovered in Thunderbird, which could
result in denial of service, the execution of arbitrary code or spoofing
of signed PGP/MIME and SMIME emails.

For the oldstable distribution (bullseye), these problems have been fixed
in version 1:115.6.0-1~deb11u1.

For the stable distribution (bookworm), these problems have been fixed in
version 1:115.6.0-1~deb12u1.

We recommend that you upgrade your thunderbird packages.
