CVE-2026-110838

FreeRDP shadow server from 3.0.0 before 3.32.0 dispatches input PDUs during the Confirm Active state before authentication, allowing unauthenticated attackers to inject keyboard input. Attackers can negotiate TLS-only RDP and send an input PDU without Confirm Active to inject synthetic keystrokes...

CVE-2026-110839

FreeRDP 3.3.0 before 3.32.0, when built with WINPRUTILSIMAGEJPEG=ON, has a heap-based out-of-bounds write in winprconvertfromjpeg because grayscale JPEG buffers are sized from one input component rather than three BGR output components. A malicious RDP server can offer a grayscale JPEG via...

DEBIAN-CVE-2026-110834

FreeRDP from 2.0.0 before 3.32.0 contains a null pointer dereference vulnerability that allows malicious RDP servers to crash clients by sending out-of-lifecycle serial IRPs. Attackers can send IRPMJREAD or IRPMJWRITE before create or after close, causing CommReadFile or CommWriteFile to...

DEBIAN-CVE-2026-110837

FreeRDP 2.0.0 before 3.32.0, when built with WITHLAME=ON and WITHDSPFFMPEG=OFF, has a heap-based buffer overflow in freerdpdspdecodemp3 because the right-channel PCM pointer is offset by a byte count treated as short elements. A malicious RDP server can send MP3 audio over rdpsnd so decoded sampl...

DEBIAN-CVE-2026-110832

FreeRDP from 2.0.0 before 3.32.0 contains a memory exhaustion vulnerability in wtsreaddrdynvcdatafirst that allows authenticated clients to force servers to commit large memory allocations. Attackers can send a seven-byte DATAFIRST message on an opened DVC declaring a large 32-bit length, causing...

DEBIAN-CVE-2026-110835

FreeRDP 3.0.0 before 3.32.0 allows HTTP header injection in its proxy because a lone LF in the target portion of a routing token Cookie: msts= is not rejected and is written by httpproxyconnect into the CONNECT request line and Host header. A remote unauthenticated RDP client connecting to a prox...

DEBIAN-CVE-2026-110833

FreeRDP from 3.0.0-beta1 before 3.32.0 fails to enforce cumulative or absolute size limits when reassembling RDPDR channel fragments in the proxy. Attackers can send a FIRST fragment followed by continuation fragments without LAST, growing per-session heap streams proportional to traffic and...

DEBIAN-CVE-2026-110836

FreeRDP from 3.0.0 before 3.32.0 contains an infinite loop vulnerability in httpresponserecv that allows malicious gateways to exhaust client CPU via crafted Content-Type headers. Attackers controlling a gateway can return a nonzero Content-Length with a semicolon-containing unrecognized...

DEBIAN-CVE-2026-110830

FreeRDP before 3.32.0 fails to close prior serial handles in serialprocessirpcreate, allowing a malicious RDP server to exhaust file descriptors. Attackers can send repeated serial IRPMJCREATE requests to accumulate descriptors and terminate the client at the CommReadFile FDSETSIZE assertion...

DEBIAN-CVE-2026-110829

FreeRDP versions from 3.0.0 before 3.32.0 contain a null pointer dereference in the rdpsnd channel when a fragment sets CHANNELFLAGLAST without CHANNELFLAGFIRST. A malicious RDP server can send a malformed rdpsnd PDU on a fresh channel to crash the client and cause denial of service...

DEBIAN-CVE-2026-110831

FreeRDP versions 3.13.0 before 3.32.0 contain a resource retention flaw in driveprocessirpcreate, which registers an opened local file in the drive dictionary before applying the allocation size and does not remove it when that operation fails. A malicious RDP server connected to a client with...
