CVE-2017-16927 (opens in a new tab)How to fix?
Upgrade Debian:12 xrdp to version 0.9.4-3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream xrdp package and not the xrdp package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
The scp_v0s_accept function in sesman/libscp/libscp_v0.c in the session manager in xrdp through 0.9.4 uses an untrusted integer as a write length, which allows local users to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted input stream.
