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. Prior to version 3.20.1, the NDR array reader in RDPEAR did not perform bounds checking on the number of on-wire elements, and could write beyond the heap buffer allocated from hints, resulting in a heap buffer overflow in...

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 3.20.1, there was a race in the serial channel IRP thread tracking that allowed for a heap use-after-free condition when one thread removed an entry from serial-IrpThreads while another read it. This vulnerability h...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, there was an integer underflow issue in the updatereadcachebitmaporder function of FreeRDP’s Core Library. This vulnerability has been fixed in version 3.24.0...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, a underflow of a 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 decode...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Clients and servers that use versions of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read vulnerabilities. Versions 3.5.0 and 2.11.6 address this issue. There are no known workarounds available...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol RDP, released under the Apache license. The affected versions are vulnerable to a Out-of-Bounds Read vulnerability in the nscrledecompressdata function. This vulnerability occurs because the function processes context-Planes without...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol RDP, released under the Apache license. The affected versions are vulnerable to an Out-of-Bounds Write vulnerability in the progressivedecompress function. This issue is likely due to incorrect calculations of the nXSrc and nYSrc...

Astra Linux – Vulnerability in freerdp2

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 error in the gdimultiopaquerect function. Specifically, there is no code to validate whether the value...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Clients that use versions of FreeRDP before 3.5.0 or 2.11.6 are vulnerable to integer overflows and out-of-bounds writes. Versions 3.5.0 and 2.11.6 address this issue. As a workaround, do not use /gfx options for example, deactivate...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free remote desktop protocol library and client. In affected versions, there is an out-of-bound read in the ZGFX decoder component of FreeRDP. A malicious server can trick a FreeRDP-based client into reading out-of-bound data and attempting to decode it, potentially leading to a cras...

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 3.24.0, a client-side heap buffer overflow occurred in the FreeRDP client’s AVC420/AVC444 YUV-to-RGB conversion process. This issue arose due to a lack of validation of the horizontal bounds of the H.264 metablock...

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, 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, the gdisurfacebits function processed SURFACEBITSCOMMAND messages sent by the RDP server. When these commands were processed using NSCodec, the bmp.width and bmp.height values provided by the server were not...

Important: freerdp

Issue Overview: FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, an authenticated RDP client can advertise DVI ADPCM with nBlockAlign equal to 8 and nChannels equal to 2 to make the bs calculation in rdpsndserverselectformat in channels/rdpsnd/server/rdpsndmain.c...
