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 was due to xfrailwindowcommon calling freeappWindow in case of title allocation failures, without first removing the...

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, xfSetWindowMinMaxInfo dereferenced a freed xfAppWindow pointer because xfrailgetwindow in xfrailserverminmaxinfo returned an unprotected pointer from the railWindows hash table. This could allow the main...

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 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...

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 3.23.0, 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 3.24.2, 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, the progressivedecompresstileupgrade function detected mismatches using progressiverfxquantcmpequal, but only emitted a WLogWARN message; execution continued. The wrapped value 247 was used as a shift...

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 3.24.2, 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 3.24.2, 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 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 3.21.0, 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. 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, 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 3.24.0, 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 3.20.1, 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 3.23.0, 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. 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...
