FreeBSD : FreeRDP -- Integer overflow in RDPEGFX channel (a955cdb7-d089-11ea-8c6f-080027eedc6a)

low Nessus Plugin ID 139111

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Bernhard Miklautz reports :

- Integer overflow due to missing input sanitation in rdpegfx channel

- All FreeRDP clients are affected

- The input rectangles from the server are not checked against local surface coordinates and blindly accepted. A malicious server can send data that will crash the client later on (invalid length arguments to a memcpy)

Solution

Update the affected package.
