medium Tenable Self-Hosted Container Security Plugin ID 427117

Description

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

 - xrdp is an open source remote desktop protocol (RDP) server. In versions prior to 0.9.23 improper handling
 of session establishment errors allows bypassing OS-level session restrictions. The `auth_start_session`
 function can return non-zero (1) value on, e.g., PAM error which may result in in session restrictions
 such as max concurrent sessions per user by PAM (ex ./etc/security/limits.conf) to be bypassed. Users
 (administrators) don't use restrictions by PAM are not affected. This issue has been addressed in release
 version 0.9.23. Users are advised to upgrade. There are no known workarounds for this issue.
