freerdp: FreeRDP: Arbitrary code execution via heap buffer overflow in GDI surface pipeline

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A malicious RDP server can exploit a heap buffer overflow vulnerability by sending a specially crafted graphics command to a FreeRDP client. This allows the server to write data outside of its intended memory...

freerdp: FreeRDP: Arbitrary code execution via heap out-of-bounds write in RLE planar decode path

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A malicious RDP server can exploit a heap out-of-bounds write vulnerability in the planardecompressplanerle function. This vulnerability allows the server to write past the end of a temporary buffer, potentiall...

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...

freerdp: FreeRDP heap-buffer-overflow

A heap based buffer overflow has been discovered in FreeRDP. Prior to 3.20.1, a malicious RDP server can trigger a heap-buffer-overflow write in the FreeRDP client when processing Audio Input AUDIN format lists. audinprocessformats reuses callback-formatscount across multiple MSGSNDINFORMATS PDUs...

Medium: freerdp

Issue Overview: FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, a client-side heap buffer overflow occurs in the FreeRDP client's AVC420/AVC444 YUV-to-RGB conversion path due to missing horizontal bounds validation of H.264 metablock regionRects coordinates. In...
