CVE-2020-1765

An improper control of parameters allows the spoofing of the from
fields of the following screens: AgentTicketCompose,
AgentTicketForward, AgentTicketBounce.

CVE-2020-1766

Due to improper handling of uploaded images it is possible in very
unlikely and rare conditions to force the agents browser to execute
malicious JavaScript from a special crafted SVG file rendered as
inline jpg file.

CVE-2020-1767

Unauthorized view of drafts, change the text completely and send it in
the name of draft owner. For the customer it will not be visible that
the message was sent by another agent.

For Debian 8 'Jessie', these problems have been fixed in version
3.3.18-1+deb8u13.

We recommend that you upgrade your otrs2 packages.
