Alpine: multiple xrdp packages: security update to 0.9.13-r0 (deprecated)

high Tenable Cloud Security Plugin ID 400362

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2020-4044)
