Title
FreeRDP before 3.31.0 Information Disclosure via RDPGFX ResetGraphics
Summary
FreeRDP versions before 3.31.0 contain an information disclosure vulnerability in the RDPGFX server's ResetGraphics PDU serializer that fails to initialize padding bytes in the fixed 340-byte wire format. Attackers can receive uninitialized heap memory including live pointers and GLib function addresses transmitted in the PDU, defeating heap ASLR and disclosing the GLib module base address.

Title
FreeRDP before 3.31.0 Information Disclosure via uninitialized heap memory
Summary
FreeRDP versions 3.0.0 through 3.30.0 (before 3.31.0) transmit uninitialized heap memory in Save Session Info PDU reserved padding fields. Three PDU writers in libfreerdp/core/info.c (rdp_write_logon_info_v2, rdp_write_logon_info_plain, and rdp_write_logon_info_ex) use Stream_Seek instead of Stream_Zero for reserved pad bytes (up to 576 bytes), leaving previously freed heap contents in the outgoing PDU. Because the send buffer is allocated with malloc (not zeroed), stale heap data — which may include cleartext credentials from prior sessions — can be sent to the receiving peer. FreeRDP-based servers using rdpUpdate::SaveSessionInfo and freerdp-proxy (which forwards these PDUs) are affected, allowing disclosure of server/proxy process memory to a downstream client.

CVE-2026-84267 (GCVE-0-2026-84267)

Vulnerability from cvelistv5 – Published: 2026-09-01 15:19 – Updated: 2026-09-02 13:06

Title
Gvfs: sftp: uninitialized heap disclosure in read_string()
Summary
A flaw was found in the SFTP backend in gvfs. When mounting a share, a malicious SFTP server can cause read_string() to allocate a buffer with a certain length but the function does not verify that the buffer is completely filled, leaving the remainder of the buffer containing uninitialized heap contents. If the server sends a short FXP_HANDLE reply, these uninitialized bytes are taken as the file handle. The client will then echo these uninitialized bytes back to the server on all subsequent requests using that handle. With a length of 128 bytes, this issue allows the malicious server to deterministically read uninitialized heap memory from the gvfsd-sftp process, leaking its heap base and the load address of the libgio library, resulting in a deterministic defeat of Address Space Layout Randomization (ASLR).

Mitigation
Implementation

Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.

Mitigation
Implementation

Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.

Mitigation
Implementation

Avoid race conditions (CWE-362) during initialization routines.

Mitigation
Build and Compilation

Run or compile the product with settings that generate warnings about uninitialized variables or data.

No CAPEC attack patterns related to this CWE.
