FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, the function Stream_EnsureCapacity can create an endless blocking loop. This may affect all client and server implementations using FreeRDP. For practical exploitation this will only work on 32bit systems where the available physical memory is >= SIZE_MAX. Version 3.23.0 contains a patch. No known workarounds are available.
A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. The Stream_EnsureCapacity function can create an endless blocking loop, leading to a Denial of Service (DoS). This vulnerability can be exploited on 32-bit systems where the available physical memory is greater than or equal to the SIZE_MAX variable, potentially affecting both client and server implementations using FreeRDP.
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.
