Vulnerabilities 13
-
High 8.8
FreeRDP 3.0.0-beta1 before 3.32.0 Use-After-Free via Smartcard Connect
FreeRDP from 3.0.0-beta1 before 3.32.0 contains a use-after-free vulnerability in smartcard handling that allows attackers to access a freed smartcard handle object after an invalid connect operation. Attackers can trigger an invalid smartcard connect operati…

High 8.8
FreeRDP before 3.32.0 Heap Out-of-Bounds Write in AVC444 YUV444 Combine
FreeRDP before 3.32.0 contains a client-side heap out-of-bounds write vulnerability in general_LumaToYUV444 and general_ChromaV2ToYUV444 that allows malicious RDP servers to corrupt client memory. Attackers can send RDPGFX AVC444 or AVC444v2 frames with odd-h…
-
High 8.8
FreeRDP before 3.32.1 Heap Buffer Overflow via rdpsnd_server_select_format
FreeRDP before 3.32.1 contains a heap-based buffer overflow in the server-side rdpsnd channel because an integer wraparound in rdpsnd_server_select_format() DVI_ADPCM block-alignment arithmetic bypasses validation. A malicious RDP client can send two SNDC_FOR…
-
High 7.5
FreeRDP shadow before 3.32.0 Pre-Authentication Input Injection via Confirm Active bypass
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…
-
High 7.5
FreeRDP 3.0.0 before 3.32.0 Unauthenticated Memory Exhaustion via NLA Frame Parser
FreeRDP from 3.0.0 before 3.32.0 contains an uncontrolled resource consumption vulnerability in parse_nla_mode_pdu that allows unauthenticated attackers to exhaust server memory. Attackers can complete TLS and stream bytes not beginning with the DER SEQUENCE …
-
High 7.4
FreeRDP 2.0.0 before 3.32.0 Heap Out-of-Bounds Write via NTLM MIC Offset
FreeRDP versions from 2.0.0 before 3.32.0 contain a heap out-of-bounds write in the server hash-callback NTLM path that fails to validate the MIC offset. Unauthenticated attackers can send a crafted AUTHENTICATE_MESSAGE with a backward session-key offset and …
-
High 7.3
FreeRDP before 3.32.0 Heap Buffer Overflow via persistent_cache_read_entry_v3
FreeRDP before 3.32.0 contains a heap buffer overflow vulnerability in persistent_cache_read_entry_v3 that allows local attackers to corrupt memory by supplying a crafted v3 persistent cache file. Attackers can set large width and height values that wrap the …
-
High 7.3
FreeRDP before 3.32.0 Heap Buffer Overflow via Persistent Cache v2 Parser
FreeRDP before 3.32.0 contains a heap buffer overflow vulnerability in persistent_cache_read_entry_v2 that allows local attackers to corrupt heap memory via integer wraparound in bitmap size calculation. Attackers can craft a persistent cache v2 file with ove…
-
High 7.1
FreeRDP before 3.0.0 and 3.6.0 before 3.32.0 Uninitialized Heap Disclosure via Progressive Codec Tile Upgrade
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 WBT_TILE_FIRST then WBT_TILE_UPGRADE sequ…
-
High 7.1
FreeRDP 2.0.0 before 3.32.0 Heap Buffer Overflow via MP3 Audio Decoding
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…
-
High 7.1
FreeRDP 3.3.0 before 3.32.0 Heap Out-of-Bounds Write via Grayscale JPEG Clipboard Data
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 …
-
Medium 5.9
FreeRDP before 3.32.0 Denial of Service via Serial IRP_MJ_CREATE
FreeRDP before 3.32.0 fails to close prior serial handles in serial_process_irp_create, allowing a malicious RDP server to exhaust file descriptors. Attackers can send repeated serial IRP_MJ_CREATE requests to accumulate descriptors and terminate the client a…
-
Medium 5.9
FreeRDP before 3.32.0 Unbounded Memory Retention via RDPDR Proxy
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 st…
