CVE-2026-24677 1 Freerdp 1 Freerdp 2026-06-17 N/A 9.1 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, ecam_encoder_compress_h264 trusts server-controlled dimensions and does not validate the source buffer size, leading to an out-of-bounds read in sws_scale. This vulnerability is fixed in 3.22.0.
CVE-2026-24676 1 Freerdp 1 Freerdp 2026-06-17 N/A 7.5 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, AUDIN format renegotiation frees the active format list while the capture thread continues using audin->format, leading to a use after free in audio_format_compatible. This vulnerability is fixed in 3.22.0.
CVE-2026-24675 1 Freerdp 1 Freerdp 2026-06-17 N/A 7.5 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, urb_select_interface can free the device's MS config on error but later code still dereferences it, leading to a use after free in libusb_udev_select_interface. This vulnerability is fixed in 3.22.0.
CVE-2026-24491 1 Freerdp 1 Freerdp 2026-06-17 N/A 7.5 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, video_timer can send client notifications after the control channel is closed, dereferencing a freed callback and triggering a use after free. This vulnerability is fixed in 3.22.0.
CVE-2026-23948 1 Freerdp 1 Freerdp 2026-06-17 N/A 7.5 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, a NULL pointer dereference vulnerability in rdp_write_logon_info_v2() allows a malicious RDP server to crash FreeRDP proxy by sending a specially crafted LogonInfoV2 PDU with cbDomain=0 or cbUserName=0. This vulnerability is fixed in 3.22.0.
CVE-2026-23732 1 Freerdp 1 Freerdp 2026-06-17 N/A 7.5 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, FastGlyph parsing trusts `cbData`/remaining length and never validates against the minimum size implied by `cx/cy`. A malicious server can trigger a client‑side global buffer overflow, causing a crash (DoS). Version 3.21.0 contains a patch for the issue.
CVE-2026-22857 1 Freerdp 1 Freerdp 2026-06-17 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a heap use-after-free occurs in irp_thread_func because the IRP is freed by irp->Complete() and then accessed again on the error path. This vulnerability is fixed in 3.20.1.
CVE-2026-22856 1 Freerdp 1 Freerdp 2026-06-17 N/A 8.1 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a race in the serial channel IRP thread tracking allows a heap use‑after‑free when one thread removes an entry from serial->IrpThreads while another reads it. This vulnerability is fixed in 3.20.1.
CVE-2026-22854 1 Freerdp 1 Freerdp 2026-06-17 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a heap-buffer-overflow occurs in drive read when a server-controlled read length is used to read file data into an IRP output stream buffer without a hard upper bound, allowing an oversized read to overwrite heap memory. This vulnerability is fixed in 3.20.1.
CVE-2026-22852 1 Freerdp 1 Freerdp 2026-06-17 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a malicious RDP server can trigger a heap-buffer-overflow write in the FreeRDP client when processing Audio Input (AUDIN) format lists. audin_process_formats reuses callback->formats_count across multiple MSG_SNDIN_FORMATS PDUs and writes past the newly allocated formats array, causing memory corruption and a crash. This vulnerability is fixed in 3.20.1.
CVE-2026-22851 1 Freerdp 1 Freerdp 2026-06-17 N/A 5.9 MEDIUM
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a race condition between the RDPGFX dynamic virtual channel thread and the SDL render thread leads to a heap use-after-free. Specifically, an escaped pointer to sdl->primary (SDL_Surface) is accessed after it has been freed during RDPGFX ResetGraphics handling. This vulnerability is fixed in 3.20.1.
CVE-2025-68118 1 Freerdp 1 Freerdp 2026-06-17 N/A 9.1 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.0, a vulnerability exists in FreeRDP’s certificate handling code on Windows platforms. The function `freerdp_certificate_data_hash_ uses` the Microsoft-specific `_snprintf` function to format certificate cache filenames without guaranteeing NUL termination when truncation occurs. According to Microsoft documentation, `_snprintf` does not append a terminating NUL byte if the formatted output exceeds the destination buffer size. If an attacker controls the hostname value (for example via server redirection or a crafted .rdp file), the resulting filename buffer may not be NUL-terminated. Subsequent string operations performed on this buffer may read beyond the allocated memory region, resulting in a heap-based out-of-bounds read. In default configurations, the connection is typically terminated before sensitive data can be meaningfully exposed, but unintended memory read or a client crash may still occur under certain conditions. Version 3.20.0 has a patch for the issue.
CVE-2024-32662 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2026-06-17 N/A 7.5 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients prior to version 3.5.1 are vulnerable to out-of-bounds read. This occurs when `WCHAR` string is read with twice the size it has and converted to `UTF-8`, `base64` decoded. The string is only used to compare against the redirection server certificate. Version 3.5.1 contains a patch for the issue. No known workarounds are available.
CVE-2024-32661 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2026-06-17 N/A 7.5 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients prior to version 3.5.1 are vulnerable to a possible `NULL` access and crash. Version 3.5.1 contains a patch for the issue. No known workarounds are available.
CVE-2024-32660 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2026-06-17 N/A 7.5 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.5.1, a malicious server can crash the FreeRDP client by sending invalid huge allocation size. Version 3.5.1 contains a patch for the issue. No known workarounds are available.
CVE-2024-32659 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2026-06-17 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients prior to version 3.5.1 are vulnerable to out-of-bounds read if `((nWidth == 0) and (nHeight == 0))`. Version 3.5.1 contains a patch for the issue. No known workarounds are available.
CVE-2024-32658 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2026-06-17 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients prior to version 3.5.1 are vulnerable to out-of-bounds read. Version 3.5.1 contains a patch for the issue. No known workarounds are available.
CVE-2024-32460 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2026-06-17 N/A 8.1 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based based clients using `/bpp:32` legacy `GDI` drawing path with a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, use modern drawing paths (e.g. `/rfx` or `/gfx` options). The workaround requires server side support.
CVE-2024-32459 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2026-06-17 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients and servers that use a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch the issue. No known workarounds are available.
CVE-2024-32458 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2026-06-17 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients that use a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, use `/gfx` or `/rfx` modes (on by default, require server side support).
