Debian DSA-5502-1 : xrdp - security update

critical Nessus Plugin ID 181564

Language:

Synopsis

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

Description

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-5502 advisory.

Multiple security vulnerabilities have been found in xrdp, a remote desktop protocol server. Buffer overflows and out-of-bound writes may cause a denial of service or other unspecified impact. For the oldstable distribution (bullseye), these problems have been fixed in version 0.9.21.1-1~deb11u1. We recommend that you upgrade your xrdp packages. For the detailed security status of xrdp please refer to its security tracker page at: https://security-tracker.debian.org/tracker/xrdp

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the xrdp packages.
