DEBIAN-CVE-2026-109250

FreeRDP 3.0.0 before 3.32.0 contains a heap buffer overflow vulnerability in collectkeys that allows local attackers to write past the fixed 64-entry keys array during PKCS11 key enumeration. Attackers controlling smartcard tokens can present more than 64 public key objects across multiple slots ...

DEBIAN-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...

DEBIAN-CVE-2026-109255

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...

DEBIAN-CVE-2026-109251

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 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...

DEBIAN-CVE-2026-109244

FreeRDP from 2.0.0 before 3.32.0 contains an insecure permission vulnerability in winpr-makecert that creates unencrypted private keys without owner-only file modes. Local users on multi-user Unix hosts can read world-readable key files or open PFX files protected by the hard-coded default passwo...

DEBIAN-CVE-2026-109246

FreeRDP before 3.32.0 contains a divide-by-zero vulnerability in the freerdp-shadow-cli shadow server: the frame id in a client's Frame Acknowledge PDU is stored without a range check, so the in-flight frame count in shadowencoderinflightframes can underflow. An authenticated client can acknowled...

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...

CVE-2026-109243

FreeRDP from 3.0.0 before 3.32.0 contains an incorrect permission assignment vulnerability that allows local users to read private keys written by cryptowritepem without owner-only permissions. Attackers on multi-user Unix hosts can enumerate the shared temporary directory during soft-smartcard...

DEBIAN-CVE-2026-109242

FreeRDP before 3.0.0 and 3.6.0 before 3.32.0 renders uninitialized heap memory from un-decoded progressive tiles because the tile-current buffer is allocated without zeroing. A malicious RDP server can send a crafted WBTTILEFIRST then WBTTILEUPGRADE sequence to paint heap bytes onscreen or abort...

DEBIAN-CVE-2026-109245

FreeRDP 3.0.0 before 3.32.0 contains an improper certificate validation vulnerability in freerdphttprequest in libfreerdp/utils/http.c that completes TLS handshakes without verifying the server certificate chain. On-path attackers can impersonate login.microsoftonline.com in the Azure AD...
