CVE-2026-109255 FreeRDP 3.0.0 before 3.32.0 heap buffer overflow via license_check_stream_length

FreeRDP 3.0.0 before 3.32.0 contains an integer truncation vulnerability in licensecheckstreamlength that allows a malicious RDP server to trigger a heap buffer overflow on 32-bit clients. Attackers can send a crafted SERVERLICENSEREQUEST with a large scopeCount that bypasses length checks, causi...

EUVD-2026-97697

FreeRDP from 3.9.0 before 3.32.0 contains an out-of-bounds read vulnerability in the RDPEAR NDR scalar readers, which check value length before consuming alignment padding. Malicious or compromised RDP servers can send crafted unaligned RDPEAR payloads, such as CreateApReqAuthenticatorReq message...

CVE-2026-109253 FreeRDP 3.9.0 before 3.32.0 RDPEAR NDR Scalar Out-of-Bounds Read

FreeRDP from 3.9.0 before 3.32.0 contains an out-of-bounds read vulnerability in the RDPEAR NDR scalar readers, which check value length before consuming alignment padding. Malicious or compromised RDP servers can send crafted unaligned RDPEAR payloads, such as CreateApReqAuthenticatorReq message...

CVE-2026-109253 FreeRDP 3.9.0 before 3.32.0 RDPEAR NDR Scalar Out-of-Bounds Read

CVE-2026-109253

FreeRDP versions 3.9.0 before 3.32.0 are vulnerable to an out-of-bounds read in the RDPEAR NDR scalar readers. The flaw occurs because the software checks value length before consuming alignment padding. A malicious or compromised RDP server can send crafted unaligned RDPEAR payloads, such as Cre...

CVE-2026-109253

FreeRDP from 3.9.0 before 3.32.0 contains an out-of-bounds read vulnerability in the RDPEAR NDR scalar readers, which check value length before consuming alignment padding.

CVE-2026-109252

FreeRDP versions 3.9.0 before 3.32.0 are vulnerable to a NULL pointer dereference within the RDPEAR NDR reader . A malicious server can trigger this by sending a CreateApReqAuthenticatorReq with a NameCount of two or more that ends before the Names pointer. This causes the cleanup process to dere...

CVE-2026-109251

FreeRDP versions prior to 3.32.0 are vulnerable to an Out-of-Bounds Write due to improper validation of server-supplied MS-RDPEGT geometry origin. The issue occurs because the software stores this origin in an unsigned video surface coordinate, causing the blit clamp in gdiVideoShowSurface() to w...

EUVD-2026-97695

FreeRDP before 3.32.0 stores the server-supplied signed MS-RDPEGT geometry origin unchecked in an unsigned video surface coordinate, so the blit clamp in gdiVideoShowSurface wraps in 32-bit arithmetic and is skipped. A malicious RDP server can send a negative topLevelLeft to clients connecting wi...

CVE-2026-109252 FreeRDP from 3.9.0 before 3.32.0 RDPEAR NULL Pointer Dereference via KERB_RPC_INTERNAL_NAME

FreeRDP from 3.9.0 before 3.32.0 contains a NULL pointer dereference vulnerability in the RDPEAR NDR reader that allows malicious servers to crash clients via truncated KERBRPCINTERNALNAME data. Attackers can send a CreateApReqAuthenticatorReq with NameCount of two or more ending before the Names...
