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. 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-2026-109251

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-2026-109248

FreeRDP versions 3.0.0 before 3.32.0 are vulnerable to a heap out-of-bounds read within the WinPR clipboard function convert_filedescriptors_to_file_list(). The flaw occurs because the function performs unbounded _wcschr() and count_special_chars() calls on a server-controlled FILEDESCRIPTORW cFi...

CVE-2026-109249

The software FreeRDP 3.0.0 before 3.32.0 is vulnerable to a heap out-of-bounds read within the freerdp_assistance_parse_all_elements_of() function. The root cause is that the parser advances its cursor without reducing the remaining length, allowing the scan window to exceed the decrypted Connect...

CVE-2026-109248

FreeRDP 3.0.0 before 3.32.0 contains a heap out-of-bounds read in the WinPR clipboard function convertfiledescriptorstofilelist, which scans a server-controlled FILEDESCRIPTORW cFileName with unbounded wcschr and countspecialchars calls without a NUL-termination guarantee. A malicious RDP server...
