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 subject to an Out-of-Bounds Read in the generalLumaToYUV444 function. This Out-of-Bounds Read occurs because processing is performed on the in variable without checkin...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Clients that rely on FreeRDP before version 3.5.1 are vulnerable to out-of-bounds read attacks if nWidth == 0 and nHeight == 0. Version 3.5.1 includes a patch for this issue. There are no known workarounds available...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfcliprdrprovidedata passed the freed pDstData to XChangeProperty. This was because the cliprdr channel thread called xfcliprdrserverformatdataresponse, which converted and used the clipboard data without...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, a capture thread sent sample responses using a freed channel callback after a device channel was closed, resulting in a use of memory after deallocation in ecamchannelwrite. This vulnerability has been fixed...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in yuvensurebuffer in libfreerdp/codec/h264.c, h264-width and h264-height were updated before the reallocation loop. If any winpralignedrecalloc call fails, the function returns FALSE, but width/height have...

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 out-of-bounds read/write occurred in FreeRDP’s bitmap cache subsystem due to an off-by-one boundary check in bitmapcacheput. A malicious server could send a CACHEBITMAPORDER Rev1 with a...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, the ecamencodercompressh264 function relied on server-controlled dimensions and did not validate the source buffer size, resulting in a out-of-bounds read in swsscale. This vulnerability has been fixed in...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in the persistentcachereadentryv3 function in libfreerdp/cache/persistent.c, persistent-bmpSize was updated before winpralignedrecalloc. If realloc fails, bmpSize is inflated while bmpData points to the old...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free remote desktop protocol library and client. Affected versions of FreeRDP lack input validation in the urbdrc channel. A malicious server can trick a FreeRDP-based client into crashing due to a division by zero. This issue has been addressed in version 2.9.0. All users are advise...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free remote desktop protocol library and clients. Affected versions of FreeRDP lack input length validation in the urbdrc channel. A malicious server can trick a FreeRDP-based client into reading out-of-bound data and sending it back to the server. This issue has been addressed in...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, pixel data from adjacent heap memory was rendered to the screen, potentially exposing sensitive data to attackers. This issue has been fixed in version 3.24.2...

Astra Linux – Vulnerability in freerdp3, freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, the RDPSND async playback thread could process queued PDUs after the channel was closed and its internal state was freed, resulting in a use after free in rdpsndtreatwave. This vulnerability has been fixed i...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, there was a buffer overflow vulnerability in the MS-ADPCM and IMA-ADPCM decoders, due to unchecked predictor and stepindex values from input data. 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 3.20.1, a memory access violation occurred in irpthreadfunc because the IRP was freed by irp-Complete, and then accessed again during the error handling path. 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 3.24.0, 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 3.20.1, a global-buffer-overflow issue was observed during FreeRDP’s Base64 decoding process. The root cause appears to be implementation-defined char signedness: on Arm/AArch64 builds, plain char values are treated...
