Arch Linux Security Advisory ASA-202110-11 ========================================== Severity: Medium Date : 2021-10-29 CVE-ID : CVE-2021-41159 CVE-2021-41160 Package : freerdp Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-2488 Summary ======= The package freerdp before version 2:2.4.1-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 2:2.4.1-1. # pacman -Syu "freerdp>=2:2.4.1-1" The problems have been fixed upstream in version 2.4.1. Workaround ========== CVE-2021-41159 can be mitigated by using a /gt:http connection or a direct connection without gateway. No known mitigation exists for CVE-2021-41160. Description =========== - CVE-2021-41159 (arbitrary code execution) A security issue has been found in FreeRDP before version 2.4.1. Improper client input validation for gateway connections (/gt:rpc) allows a malicious gateway to overwrite client memory. - CVE-2021-41160 (arbitrary code execution) A security issue has been found in FreeRDP before version 2.4.1. A malicious server might trigger out of bound writes in a connected client. Connections using GDI or SurfaceCommands to send graphics updates to the client might send 0 width/height or out of bound rectangles to trigger out of bound writes. With 0 width or heigth the memory allocation will be 0 but the missing bounds checks allow writing to the pointer at this (not allocated) region. Impact ====== A malicious RDP server or gateway could cause remote code execution on a connected client.
