FreeRDP RDP Buffer Overflow DoS

The vulnerability of the freerdpbitmapdecompressplanar function in the RDP client FreeRDP is related to reading data beyond the buffer boundaries in memory. Exploiting this vulnerability could allow a malicious actor to cause service failures...

CVE-2026-31897

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, there is an out-of-bounds read in freerdpbitmapdecompressplanar when SrcSize is 0. The function dereferences srcp which points to pSrcData without first verifying that SrcSize = 1. When SrcSize is 0 and pSrcData is...
