CVE-2020-1770

Support bundle generated files could contain sensitive information
that might be unwanted to be disclosed.

CVE-2020-1772

It’s possible to craft Lost Password requests with wildcards in
the Token value, which allows attacker to retrieve valid Token(s),
generated by users which already requested new passwords.

CVE-2020-1774

When user downloads PGP or S/MIME keys/certificates, exported file has
same name for private and public keys. Therefore it’s possible
to mix them and to send private key to the third-party instead of
public key.

For Debian 8 'Jessie', these problems have been fixed in version
3.3.18-1+deb8u15.

We recommend that you upgrade your otrs2 packages.
