Version: CVE-2020-4044
Severity: grave
Tags: security upstream
Hi,
The following vulnerability was published for xrdp.
CVE-2020-4044[0]:
| The xrdp-sesman service before version 0.9.13.1 can be crashed by
| connecting over port 3350 and supplying a malicious payload. Once the
| xrdp-sesman process is dead, an unprivileged attacker on the server
| could then proceed to start their own imposter sesman service
| listening on port 3350. This will allow them to capture any user
| credentials that are submitted to XRDP and approve or reject arbitrary
| login credentials. For xorgxrdp sessions in particular, this allows an
| unauthorized user to hijack an existing session. This is a buffer
| overflow attack, so there may be a risk of arbitrary code execution as
| well.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Sorry for the broken report (not sure how I managed to do that broken
version using), fixing the metadata.
