FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. The xfreerdp client can connect to RDP servers such as Microsoft Windows machines, xrdp, and VirtualBox.

Security Fix(es):

  • freerdp: improper client input validation for gateway connections allows to overwrite memory (CVE-2021-41159)

  • freerdp: improper region checks in all clients allow out of bound write to memory (CVE-2021-41160)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
