https://notcve.org/view.php?id=CVE-2024-32039
22 Apr 2024 — FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients using a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to integer overflow and out-of-bounds write. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, do not use `/gfx` options (e.g. deactivate with `/bpp:32` or `/rfx` as it is on by default). FreeRDP es una implementación gratuita del protocolo de escritorio remoto. • https://github.com/FreeRDP/FreeRDP/pull/10077 • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2024-22211
19 Jan 2024 — FreeRDP is a set of free and open source remote desktop protocol library and clients. In affected versions an integer overflow in `freerdp_bitmap_planar_context_reset` leads to heap-buffer overflow. This affects FreeRDP based clients. FreeRDP based server implementations and proxy are not affected. A malicious server could prepare a `RDPGFX_RESET_GRAPHICS_PDU` to allocate too small buffers, possibly triggering later out of bound read/write. • https://github.com/FreeRDP/FreeRDP/commit/939e922936e9c3ae8fc204968645e5e7563a2fff • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •

31 Aug 2023 — FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Write in the `clear_decompress_bands_data` function in which there is no offset validation. Abuse of this vulnerability may lead to an out of bounds write. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. there are no known workarounds for this vulnerability. • https://github.com/FreeRDP/FreeRDP/blob/5be5553e0da72178a4b94cc1ffbdace9ceb153e5/libfreerdp/codec/clear.c#L612-L618 • CWE-787: Out-of-bounds Write •

31 Aug 2023 — FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Write in the `progressive_decompress` function. This issue is likely down to incorrect calculations of the `nXSrc` and `nYSrc` variables. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3.

31 Aug 2023 — FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Read in the `general_LumaToYUV444` function. This Out-Of-Bounds Read occurs because processing is done on the `in` variable without checking if it contains data of sufficient length. Insufficient data for the `in` variable may cause errors or crashes. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. • https://github.com/FreeRDP/FreeRDP/blob/5be5553e0da72178a4b94cc1ffbdace9ceb153e5/libfreerdp/codec/nsc.c#L115-L175 • CWE-125: Out-of-bounds Read •

31 Aug 2023 — FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an IntegerOverflow leading to Out-Of-Bound Write Vulnerability in the `gdi_CreateSurface` function. This issue affects FreeRDP based clients only. FreeRDP proxies are not affected as image decoding is not done by a proxy. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. • https://github.com/FreeRDP/FreeRDP/blob/fee2b10ba1154f952769a53eb608f044782e22f8/libfreerdp/gdi/gfx.c#L1156-L1165 • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

31 Aug 2023 — FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. In affected versions a missing offset validation may lead to an Out Of Bound Read in the function `gdi_multi_opaque_rect`. In particular there is no code to validate if the value `multi_opaque_rect->numRectangles` is less than 45. Looping through `multi_opaque_rect->`numRectangles without proper boundary checks can lead to Out-of-Bounds Read errors which will likely lead to a crash.

31 Aug 2023 — FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an invalid offset validation leading to Out Of Bound Write. This can be triggered when the values `rect->left` and `rect->top` are exactly equal to `surface->width` and `surface->height`. eg. `rect->left` == `surface->width` && `rect->top` == `surface->height`. In practice this should cause a crash. • https://github.com/FreeRDP/FreeRDP/blob/63a2f65618748c12f79ff7450d46c6e194f2db76/libfreerdp/gdi/gfx.c#L1219-L1239 • CWE-787: Out-of-bounds Write •

31 Aug 2023 — FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to a missing offset validation leading to Out Of Bound Read. In the `libfreerdp/codec/rfx.c` file there is no offset validation in `tile->quantIdxY`, `tile->quantIdxCb`, and `tile->quantIdxCr`. As a result crafted input can lead to an out of bounds read access which in turn will cause a crash.
