Package        : xrdp
CVE ID         : CVE-2020-4044
Debian Bug     : 964573

Ashley Newson discovered that the XRDP sessions manager was susceptible
to denial of service. A local attacker can further take advantage of
this flaw to impersonate the XRDP sessions manager and capture any user
credentials that are submitted to XRDP, approve or reject arbitrary
login credentials or to hijack existing sessions for xorgxrdp sessions.

For the stable distribution (buster), this problem has been fixed in
version 0.9.9-1+deb10u1.

We recommend that you upgrade your xrdp packages.

For the detailed security status of xrdp please refer to its security
tracker page at:
