CVE-2024-32460: FreeRDP Out-Of-Bounds Read in interleaved_decompress
First published: Mon 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.
