4DescriptionGitHub Advisory
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a race condition between the RDPGFX dynamic virtual channel thread and the SDL render thread leads to a heap use-after-free. Specifically, an escaped pointer to sdl->primary (SDL_Surface) is accessed after it has been freed during RDPGFX ResetGraphics handling. This vulnerability is fixed in 3.20.1.
AnalysisAI
FreeRDP versions prior to 3.20.1 contain a race condition between the RDPGFX virtual channel and SDL rendering threads that enables heap use-after-free when graphics are reset. Public exploit code exists for this vulnerability, allowing attackers to crash the application or potentially execute code in industrial control systems and other environments using vulnerable FreeRDP implementations. A patch is not currently available, leaving affected systems exposed until an update is released.
Technical ContextAI
Classified as CWE-362 (Race Condition). Affects Freerdp. FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a race condition between the RDPGFX dynamic virtual channel thread and the SDL render thread leads to a heap use-after-free. Specifically, an escaped pointer to sdl->primary (SDL_Surface) is accessed after it has been freed during RDPGFX ResetGraphics handling. This vulnerability is fixed in 3.20.1.
RemediationAI
Fixed in version 3.20.1.. Restrict network access to the affected service where possible.
