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

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 3.24.2, 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 before version 3.22.0 contains a use-after-free vulnerability in the dvcmanchannelclose and dvcmancallonreceive functions, due to improper synchronization of channel callback access. A malicious RDP server can trigger a race condition by sending DYNVCDATA and DYNVCCLOSE messages...

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 malicious RDP server could trigger a heap-buffer-overflow write in the FreeRDP client when processing Audio Input AUDIN format lists. The audinprocessformats function reuses the callback-formatscount...

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 3.23.0, xfAppUpdateWindowFromSurface read data from a freed xfAppWindow, because the RDPGFX DVC thread obtained a bare pointer via xfrailgetwindow without any lifetime protection. Meanwhile, the main thread could...

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 freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, railwindowfree dereferenced a freed xfAppWindow pointer during HashTableFree cleanup. This occurred because xfrailwindowcommon called freeappWindow in case of title allocation failures, without first removin...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.1, a race condition between the RDPGFX dynamic virtual channel thread and the SDL rendering thread led to a heap use-after-free. Specifically, a pointer to sdl-primary SDLSurface was accessed after it had been...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, asynchronous bulk transfer operations could cause a freed channel callback to be used after the URBDRC channel was closed, resulting in an use-after-free condition in the urbwritecompletion function. This...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, urbselectinterface could free the device’s MS config upon an error, but subsequent code still dereferenced it, resulting in a use after free in libusbudevselectinterface. This vulnerability has been fixed in...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, 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 3.21.0, a client-side heap buffer overflow occurred in the gdiSurfaceToSurface path of the FreeRDP client due to a mismatch between destination rectangle clamping and the actual copy size. A malicious server can...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, FastGlyph parsing relied on cbData/remaining length, and never validated against the minimum size implied by cx/cy. A malicious server could trigger a client-side global buffer overflow, resulting in a crash...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Versions on the 2.x branch prior to 2.11.8, as well as versions on the 3.x branch prior to 3.23.0, have a out-of-bounds read vulnerability in the FreeRDP client’s RDPGFX channel. This vulnerability allows a malicious RDP server to...

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 3.22.0, audinserverrecvformats freed an incorrect number of audio formats upon parse failure i + i, resulting in out-of-bounds access in audioformatsfree. This vulnerability has been fixed in version 3.22.0...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfrailserverlocalmovesize dereferenced a freed xfAppWindow pointer because xfrailgetwindow returned an unprotected pointer from the railWindows hash table. This could allow the main thread to delete the wind...
