CVE-2020-15103

Publication date 27 July 2020

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Cvss 3 Severity Score

3.5 · Low

Score breakdown

In FreeRDP less than or equal to 2.1.2, an integer overflow exists 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`) This has been fixed in 2.2.0. As a workaround, stop using command line arguments /gfx, /gfx-h264 and /network:auto

Notes

mdeslaur

The freerdp package in Ubuntu 16.04 LTS and Ubuntu 18.04 LTS does not build a server library. This is simply a client denial of service that has a negligible security impact.
