freerdp: FreeRDP has a division-by-zero in ADPCM decoders when `nBlockAlign` is 0

A division by zero flaw has been discovered in FreeRDP. This division by zero exists in the MS-ADPCM and IMA-ADPCM decoders when nBlockAlign is 0, leading to a crash. In libfreerdp/codec/dsp.c, both ADPCM decoders use size % blocksize where blocksize = context-common.format.nBlockAlign. The...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free remote desktop protocol library and clients. Clients based on FreeRDP on Unix systems that use the /parallel command-line switch may read uninitialized data and send it to the server to which the client is currently connected. Server implementations based on FreeRDP are not...

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 IntegerOverflow issue, which leads to an Out-of-Bound Write Vulnerability in the gdiCreateSurface function. This issue only affects FreeRDP-based clients...

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 attack in the cleardecompressbandsdata function, where there is no offset validation. Abuse of this vulnerability could lead to an...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol RDP, released under the Apache license.

freerdp: FreeRDP has a heap-buffer-overflow in urb_select_interface

A heap buffer overflow has been discovered in FreeRDP. The URBDRC client uses server-supplied interface numbers as array indices without bounds checks, causing an out-of-bounds read in libusbudevselectinterface...

freerdp: FreeRDP: Arbitrary code execution via crafted Remote Desktop Protocol (RDP) server messages

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. The gdisurfacebits function, which processes SURFACEBITSCOMMAND messages, does not properly validate image dimensions bmp.width and bmp.height provided by a malicious RDP server. This can lead to a heap buffer...
