Title
FreeRDP 3.3.0 before 3.32.0 Heap Out-of-Bounds Write via Grayscale JPEG Clipboard Data
Summary
FreeRDP 3.3.0 before 3.32.0, when built with WINPR_UTILS_IMAGE_JPEG=ON, has a heap-based out-of-bounds write in winpr_convert_from_jpeg 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 clipboard redirection, corrupting client memory and crashing it when the item is pasted as CF_DIB bitmap data.

Title
FreeRDP shadow before 3.32.0 Pre-Authentication Input Injection via Confirm Active bypass
Summary
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 into the host user's X11 session via XTEST.

Title
FreeRDP 2.0.0 before 3.32.0 Heap Buffer Overflow via MP3 Audio Decoding
Summary
FreeRDP 2.0.0 before 3.32.0, when built with WITH_LAME=ON and WITH_DSP_FFMPEG=OFF, has a heap-based buffer overflow in freerdp_dsp_decode_mp3 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 samples cross the heap allocation, crashing the client.

FreeRDP 3.0.0 before 3.32.0 Infinite Loop DoS via Gateway Content-Type
Summary
FreeRDP from 3.0.0 before 3.32.0 contains an infinite loop vulnerability in http_response_recv() 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 Content-Type, pinning a client thread at full CPU indefinitely.

Title
FreeRDP 3.0.0 before 3.32.0 HTTP Header Injection via Proxy Routing Token
Summary
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 http_proxy_connect into the CONNECT request line and Host header. A remote unauthenticated RDP client connecting to a proxy using FixedTarget=false and an upstream HTTP proxy can alter HTTP request/header framing at that upstream proxy.

FreeRDP 2.0.0 before 3.32.0 Denial of Service via Serial IRP Null Handle
Summary
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 IRP_MJ_READ or IRP_MJ_WRITE before create or after close, causing CommReadFile or CommWriteFile to dereference a null handle and terminate clients using Linux serial redirection.

Title
FreeRDP 3.13.0 before 3.32.0 Resource Leak via Drive Redirection IRP_MJ_CREATE
Summary
FreeRDP versions 3.13.0 before 3.32.0 contain a resource retention flaw in drive_process_irp_create, 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 drive redirection enabled can send IRP_MJ_CREATE with AllocationSize set to UINT64_MAX, forcing the seek to fail and leaking the file object and operating-system handle until drive teardown.
Severity
4.3 (Medium)

Title
FreeRDP 3.0.0 before 3.32.0 Security Protocol Downgrade via Negotiation Response
Summary
The FreeRDP client 3.0.0 before 3.32.0 does not check a server-selected PROTOCOL_RDSTLS or PROTOCOL_HYBRID_EX against its enabled protocol set in nego_process_negotiation_response(), allowing a security protocol downgrade. A malicious server or man-in-the-middle can select RDSTLS to override /sec:nla pinning, complete authentication with an all-zero cookie, and receive the user's cleartext password in the Client Info PDU.
Severity
CWE
- CWE-757 - Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade')

Title
FreeRDP 3.0.0 before 3.32.0 PIN Brute-Force via Virtual Smartcard
Summary
FreeRDP 3.0.0 before 3.32.0 contains an improper restriction of excessive authentication attempts in its virtual smartcard GIDS implementation, which stores the PIN retry counter per-handle. A malicious RDP server can exhaust the counter with VERIFY APDUs, then request a new SCardConnect to reset attempts, enabling unbounded online brute-forcing of the configured smartcard PIN.

FreeRDP 3.11.0 before 3.32.0 Reachable Assertion via AVC444 Odd Region Width
Summary
FreeRDP 3.11.0 before 3.32.0 does not validate that AVC444 and AVC444v2 region widths are even before YUV444 conversion, so an odd width reaches an assertion and aborts the client. A malicious or compromised RDP server can terminate a connected FreeRDP client after RDPGFX AVC444 negotiation by sending an in-bounds region rectangle with an odd width.

Title
FreeRDP 3.3.0 before 3.32.0 Heap Out-of-Bounds Write via Grayscale JPEG Clipboard Data
Summary
FreeRDP 3.3.0 before 3.32.0, when built with WINPR_UTILS_IMAGE_JPEG=ON, has a heap-based out-of-bounds write in winpr_convert_from_jpeg 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 clipboard redirection, corrupting client memory and crashing it when the item is pasted as CF_DIB bitmap data.

Title
FreeRDP shadow before 3.32.0 Pre-Authentication Input Injection via Confirm Active bypass
Summary
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 into the host user's X11 session via XTEST.

FreeRDP 2.0.0 before 3.32.0 Heap Buffer Overflow via MP3 Audio Decoding
Summary
FreeRDP 2.0.0 before 3.32.0, when built with WITH_LAME=ON and WITH_DSP_FFMPEG=OFF, has a heap-based buffer overflow in freerdp_dsp_decode_mp3 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 samples cross the heap allocation, crashing the client.

Title
FreeRDP 3.0.0 before 3.32.0 HTTP Header Injection via Proxy Routing Token
Summary
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 http_proxy_connect into the CONNECT request line and Host header. A remote unauthenticated RDP client connecting to a proxy using FixedTarget=false and an upstream HTTP proxy can alter HTTP request/header framing at that upstream proxy.

Title
FreeRDP 3.13.0 before 3.32.0 Resource Leak via Drive Redirection IRP_MJ_CREATE
Summary
FreeRDP versions 3.13.0 before 3.32.0 contain a resource retention flaw in drive_process_irp_create, 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 drive redirection enabled can send IRP_MJ_CREATE with AllocationSize set to UINT64_MAX, forcing the seek to fail and leaking the file object and operating-system handle until drive teardown.
