Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

xrdp reports :

The scp_v0s_accept function in the session manager 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.

Solution

Update the affected packages.
