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 CVE-2020-15103 SUSE Linux Enterprise Workstation Extension 15 SP2:freerdp-2.1.2-15.10.1 SUSE Linux Enterprise Workstation Extension 15 SP2:freerdp-devel-2.1.2-15.10.1 SUSE Linux Enterprise Workstation Extension 15 SP2:libfreerdp2-2.1.2-15.10.1 SUSE Linux Enterprise Workstation Extension 15 SP2:libwinpr2-2.1.2-15.10.1 SUSE Linux Enterprise Workstation Extension 15 SP2:winpr2-devel-2.1.2-15.10.1 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2020/suse-su-20202408-1/ https://www.suse.com/security/cve/CVE-2020-15103.html CVE-2020-15103 https://bugzilla.suse.com/1174321 SUSE Bug 1174321
