FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xf_rail_server_execute_result indexes the global error_code_names[] array (7 elements, indices 0–6) with an unchecked execResult->execResult value received from the server, allowing an out-of-bounds read when the server sends an execResult value of 7 or greater. Version 3.23.0 fixes the issue.
A flaw was found in FreeRDP. A malicious server can exploit this vulnerability by sending a specially crafted execResult value (7 or greater) to the client. This unchecked value is used to index an array, leading to an out-of-bounds read in the xf_rail_server_execute_result function. This can potentially cause a denial of service in the client application.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_rail_server_execute_result` indexes the global `error_code_names[]` array (7 elements, indices 0–6) with an unchecked `execResult->execResult` value received from the server, allowing an out-of-bounds read when the server sends an `execResult` value of 7 or greater. Version 3.23.0 fixes the issue.
