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, 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, 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 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 3.22.0, 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 3.20.1, 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 3.20.1, 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 3.23.0, 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 3.20.1, 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 3.22.0, 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 3.24.2, a double-free vulnerability in the functions kerberosAcceptSecurityContext and kerberosInitializeSecurityContextA located in WinPR, winpr/libwinpr/sspi/Kerberos/kerberos.c could cause crashes in any FreeRDP...

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 3.23.0, 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, 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 3.22.0, 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 3.23.0, 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...

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 3.21.0, 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...
