CVE-2026-114043

A flaw was found in FreeRDP. WinPR's clipboard PNG-to-CFDIB synthesis allocates a bit-packed buffer for PNGs with bit depth below 8, while winprbitmapwritebuffer copies rows assuming one byte per pixel. A malicious RDP server can send a crafted low-bit-depth PNG clipboard payload that, when paste...

CVE-2026-114042

A flaw was found in FreeRDP. The drdynvc channel frees a pool-owned stream with the owned-stream deallocator when totalLength is smaller than the chunk size. A malicious RDP server can send a crafted Virtual Channel PDU to trigger the free and crash the client during teardown. This issue affects...

CVE-2026-114041

A flaw was found in FreeRDP. On Windows builds, clientclipresentgatewaymessage passes a byte count as wide-character printf precision when printing RD Gateway consent or service messages. A malicious RD Gateway can send crafted pre-authentication messages, causing the client to read beyond the...

CVE-2026-114045

A flaw was found in FreeRDP. An integer wraparound in rdpsndserverselectformat DVIADPCM block-alignment arithmetic bypasses validation in the server-side rdpsnd channel. A malicious RDP client can send crafted SNDCFORMATS PDUs, causing an unbounded heap write during server audio playback that may...

CVE-2026-114047

FreeRDP from 2.0.0 before 3.32.0 contains an improper certificate validation vulnerability in its proxy that accepts untrusted target TLS certificates when no verification module is configured. Network-positioned attackers can intercept the proxy's outbound connection and present a self-signed,...

CVE-2026-114046

FreeRDP 3.0.0 before 3.32.0 contains a null-pointer dereference in the smartcard emulation backend that accepts a null per-reader name in SCardGetStatusChange requests. A malicious RDP server can send a crafted reader-state entry with a null szReader, causing strcmp or wcscmp to crash the client...

CVE-2026-114043

FreeRDP before 3.32.1 contains a heap-based out-of-bounds read in WinPR's clipboard PNG-to-CFDIB synthesis because winprreadpngfrombuffer allocates a bit-packed buffer for PNGs with bit depth below 8, while winprbitmapwritebuffer copies rows assuming one byte per pixel. A malicious RDP server can...

CVE-2026-114045

FreeRDP before 3.32.1 contains a heap-based buffer overflow in the server-side rdpsnd channel because an integer wraparound in rdpsndserverselectformat DVIADPCM block-alignment arithmetic bypasses validation. A malicious RDP client can send two SNDCFORMATS PDUs with an nBlockAlign too small for...

CVE-2026-114044

FreeRDP before 3.32.1 contains a heap out-of-bounds read vulnerability in the Android client that allows malicious RDP servers to read beyond surface buffers by supplying unvalidated mappedWidth and mappedHeight values. Attackers can send a crafted RDPGFXMAPSURFACETOWINDOWPDU with oversized...

CVE-2026-114041

FreeRDP before 3.32.1 on Windows contains a heap out-of-bounds read in clientclipresentgatewaymessage that passes a byte count as wide-character printf precision. A malicious RD Gateway can send pre-authentication consent or service messages, causing the client to read twice the buffer size,...

CVE-2026-114042

FreeRDP 3.32.0 contains a use-after-free vulnerability in the drdynvc channel that frees a pool-owned stream with the owned-stream deallocator when totalLength is smaller than the chunk size. A malicious RDP server can send a single well-formed Virtual Channel PDU to trigger the free and crash th...
