CVE-2026-57158

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. FreeRDP clients using the Graphics GFX pipeline are vulnerable to an out-of-bounds read. A malicious RDP server can exploit this by sending a specially crafted, truncated RDPGFXCMDIDWIRETOSURFACE1 planar payloa...

CVE-2026-57157

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, FreeRDP server implementations with the MS-RDPECAM camera device enumerator channel enabled scan attacker-supplied DeviceName and VirtualChannelName fields for a NUL terminator in...

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, FreeRDP server implementations with the MS-RDPECAM camera device enumerator channel enabled scan attacker-supplied DeviceName and VirtualChannelName fields for a NUL terminator in...

CVE-2026-57158

FreeRDP (Remote Desktop Protocol client) is affected in versions 3.21.0 through 3.27.x where the GFX pipeline’s planar_decompress_plane_rle_only fix is incomplete, allowing a malicious RDP server to send a truncated RDPGFX_CMDID_WIRETOSURFACE_1 planar payload that may read one byte past the input...

EUVD-2026-43004

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.1, FreeRDP clients launched with the non-default /cache:codec:rfx option pass desktop stride and height to RemoteFX decoding for Cache Bitmap V3 data while allocating bitmap-data only for the smaller DstWidth and...

CVE-2026-55827

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.1, FreeRDP clients launched with the non-default /cache:codec:rfx option pass desktop stride and height to RemoteFX decoding for Cache Bitmap V3 data while allocating bitmap-data only for the smaller DstWidth and...

freerdp: FreeRDP: Out-of-bounds write in planar bitmap decoder allows arbitrary code execution

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. The planar bitmap decoder contains an out-of-bounds heap write vulnerability when processing RLE planar data. A remote attacker could exploit this by providing specially crafted RLE planar data, leading to an...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, in the RLE planar decode process, planardecompressplanerle wrote into pDstData at nYDst+y nDstStep + 4nXDst + nChannel, without verifying that nYDst+nSrcHeight fits within the destination height or that...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, division by zero occurred in MS-ADPCM and IMA-ADPCM decoders when nBlockAlign was 0, resulting in a crash. In libfreerdp/codec/dsp.c, both ADPCM decoders use size % blocksize, where blocksize =...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, an unvalidated authlength field read from the network triggered a WINPRASSERT failure in rtsreadauthverifiernochecks, causing any FreeRDP client connecting through a malicious RDP Gateway to crash with...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, a underflow of the sizet variable in the IMA-ADPCM and MS-ADPCM audio decoders led to a heap-buffer-overflow issue through the RDPSND audio channel. In libfreerdp/codec/dsp.c, the IMA-ADPCM and MS-ADPCM...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, xfPointerNew would free cursorPixels if there was a failure. After that, pointerfree would call xfPointerFree to free it again, which could trigger an ASan UAF. A malicious server could exploit this...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. The ainputsendinputevent function caches the channelcallback in a local variable and then uses it without synchronization. A concurrent closure of a channel can free or reinitialize the callback, resulting in an use-after-free...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in the resizevbarentry function in libfreerdp/codec/clear.c, vBarEntry-size was updated to vBarEntry-count before the winpralignedrecalloc call. If the realloc call fails, the size is inflated, and the pixel...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, there was a heap-buffer-overflow vulnerability at 24 bytes before the allocation, in the function winpralignedoffsetrecalloc. This issue has been fixed in version 3.24.2...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a malicious RDP server could trigger a heap buffer overflow in FreeRDP clients by using the GDI surface pipeline e.g., xfreerdp to send an RDPGFX ClearCodec surface command with an out-of-bounds destination...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfAppUpdateWindowFromSurface reused a cached XImage, where the data pointer referred to an RDPGFX surface buffer that had been freed. This was because gdiDeleteSurface freed surface-data without invalidating...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.1, a heap out-of-bounds read occurred in the smartcard SetAttrib path when cbAttrLen did not match the actual NDR buffer length. This vulnerability has been fixed in version 3.20.1...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a buffer overread could occur in the freerdpimagecopyfromicondata function libfreerdp/codec/color.c, due to malicious RDP window icon TSICONINFO data. This bug could be exploited over the network when a clie...
