CVE-2024-32460: FreeRDP Out-Of-Bounds Read in interleaved_decompress

Published Apr 22, 2024
·
Updated

FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based based clients using /bpp:32 legacy GDI drawing path with a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, use modern drawing paths (e.g. /rfx or /gfx options). The workaround requires server side support.
