| CVE-2026-110839 | 1 Freerdp | 1 Freerdp | 2026-10-15 | 7.1 High |
| 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. | ||||
| CVE-2026-110834 | 1 Freerdp | 1 Freerdp | 2026-10-15 | 6.5 Medium |
| 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. | ||||
| CVE-2026-110829 | 1 Freerdp | 1 Freerdp | 2026-10-15 | 6.5 Medium |
| FreeRDP versions from 3.0.0 before 3.32.0 contain a null pointer dereference in the rdpsnd channel when a fragment sets CHANNEL_FLAG_LAST without CHANNEL_FLAG_FIRST. A malicious RDP server can send a malformed rdpsnd PDU on a fresh channel to crash the client and cause denial of service. | ||||
| CVE-2026-109938 | 1 Freerdp | 1 Freerdp | 2026-10-15 | 6.5 Medium |
| Positive mapped-video coordinates overflow and abort FreeRDP clients A malicious or compromised RDP server can terminate a FreeRDP client after the user connects with video redirection enabled. | ||||
| CVE-2026-110837 | 1 Freerdp | 1 Freerdp | 2026-10-15 | 7.1 High |
| 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. | ||||
| CVE-2026-110832 | 1 Freerdp | 1 Freerdp | 2026-10-15 | 6.5 Medium |
| FreeRDP from 2.0.0 before 3.32.0 contains a memory exhaustion vulnerability in wts_read_drdynvc_data_first that allows authenticated clients to force servers to commit large memory allocations. Attackers can send a seven-byte DATA_FIRST message on an opened DVC declaring a large 32-bit length, causing zeroed resident memory growth and server resource exhaustion. | ||||
| CVE-2026-109252 | 1 Freerdp | 1 Freerdp | 2026-10-15 | 5.3 Medium |
| 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 KERB_RPC_INTERNAL_NAME data. Attackers can send a CreateApReqAuthenticatorReq with NameCount of two or more ending before the Names pointer, causing cleanup to dereference a null base and terminate the client. | ||||
| CVE-2026-109247 | 1 Freerdp | 1 Freerdp | 2026-10-15 | 3.1 Low |
| FreeRDP before 3.32.0 contains a path traversal vulnerability in convert_filedescriptors_to_file_list() in winpr/libwinpr/clipboard/synthetic_file.c, which concatenates server-supplied cFileName values from FileGroupDescriptorW clipboard data into the published local file:// URI without rejecting '/' or '..' sequences. A malicious RDP server can supply '../' sequences so the user's next clipboard paste copies an arbitrary local file readable by the client user instead of the expected remote file. | ||||
| CVE-2026-109242 | 1 Freerdp | 1 Freerdp | 2026-10-15 | 7.1 High |
| 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 sequence to paint heap bytes onscreen or abort the client process. | ||||
| CVE-2026-109948 | 1 Freerdp | 1 Freerdp | 2026-10-14 | 4.3 Medium |
| FreeRDP from 3.0.0 before 3.32.0 contains an uninitialized memory disclosure vulnerability in smartcard_Transmit_Call that allows malicious RDP servers to read client memory. Servers can send SCardTransmit requests with an invalid card handle and nonzero receive length, causing smartcard_pack_transmit_return to serialize up to 66,560 uninitialized heap bytes. | ||||
| CVE-2026-109953 | 1 Freerdp | 1 Freerdp | 2026-10-14 | 5.3 Medium |
| FreeRDP 3.0.0 before 3.32.0 contains an insufficiently protected credentials vulnerability where the /restricted-admin option fails to suppress CredSSP credential delegation, sending the cleartext password to the RDP server. A compromised or man-in-the-middle destination host can decode TSPasswordCreds and the Client Info PDU to obtain reusable administrative domain, username, and password values. | ||||
| CVE-2026-109943 | 1 Freerdp | 1 Freerdp | 2026-10-14 | 6.5 Medium |
| FreeRDP 3.29.0 before 3.32.0 contains a double free in the client's async-update message proxy, which shallow-copies the parser-owned PolygonSC or PolygonCB points array when numPoints is zero, so both the queue consumer and parser cleanup free it. A malicious RDP server can send a point-bearing polygon order followed by a zero-point order to crash a client with +async-update enabled. | ||||
| CVE-2026-109676 | 1 Freerdp | 1 Freerdp | 2026-10-14 | 8.8 High |
| 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 operation to cause reuse of the freed handle, leading to memory corruption or crashes. | ||||
| CVE-2026-109249 | 1 Freerdp | 1 Freerdp | 2026-10-13 | 5.5 Medium |
| FreeRDP 3.0.0 before 3.32.0 contains a heap out-of-bounds read in freerdp_assistance_parse_all_elements_of() because it advances its parsing cursor without reducing the remaining length, letting the scan window exceed the decrypted ConnectionString2 buffer. Attackers can supply a crafted .msrcIncident invitation file and password that crash xfreerdp when opened, before any RDP connection. | ||||
| CVE-2026-109677 | 1 Freerdp | 1 Freerdp | 2026-10-13 | 6.5 Medium |
| FreeRDP from 2.0.0-beta1 before 3.28.0 contains an out-of-bounds read vulnerability in smartcard_LocateCardsByATRA_Call because the ATR pattern cbAtr byte count is not capped. Malicious RDP servers can send crafted ATR mask arrays to use query timing as an oracle, leaking heap memory bit-by-bit to defeat ASLR and aid RCE exploits. | ||||
| CVE-2026-109253 | 1 Freerdp | 1 Freerdp | 2026-10-13 | 5.3 Medium |
| 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 messages, to clients using Remote Credential Guard, causing over-reads and potentially crashing the client process. | ||||
| CVE-2026-109244 | 1 Freerdp | 1 Freerdp | 2026-10-13 | 6.6 Medium |
| 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 password to steal private keys. | ||||
| CVE-2026-109243 | 1 Freerdp | 1 Freerdp | 2026-10-13 | 4.4 Medium |
| 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 crypto_write_pem without owner-only permissions. Attackers on multi-user Unix hosts can enumerate the shared temporary directory during soft-smartcard logon to read the world-readable PKINIT private-key copy. | ||||
| CVE-2026-109255 | 1 Freerdp | 1 Freerdp | 2026-10-13 | 6.8 Medium |
| FreeRDP 3.0.0 before 3.32.0 contains an integer truncation vulnerability in license_check_stream_length that allows a malicious RDP server to trigger a heap buffer overflow on 32-bit clients. Attackers can send a crafted SERVER_LICENSE_REQUEST with a large scopeCount that bypasses length checks, causing out-of-bounds writes leading to denial of service or remote code execution. | ||||
| CVE-2026-109250 | 1 Freerdp | 1 Freerdp | 2026-10-13 | 6.6 Medium |
| FreeRDP 3.0.0 before 3.32.0 contains a heap buffer overflow vulnerability in collect_keys() that allows local attackers to write past the fixed 64-entry keys array during PKCS#11 key enumeration. Attackers controlling smartcard tokens can present more than 64 public key objects across multiple slots to corrupt heap memory with attacker-chosen CKA_ID and CKA_LABEL data during smartcard logon. | ||||
