UBUNTU-CVE-2026-44421

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.26.0, a malicious RDP server can trigger a heap-buffer-overflow write in the FreeRDP client by sending crafted RDPGFX PDUs. The bug is in gdiCacheToSurface: it validates a destination rectangle that is clamped to UINT16MA...

UBUNTU-CVE-2026-44420

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.26.0, a malicious RDP client can trigger a heap-buffer-overflow write in FreeRDP's server-side clipboard cliprdr channel by sending a CBCLIPCAPS PDU with a too-small capabilitySetLength. This can crash the server process...

UBUNTU-CVE-2026-45700

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.26.0, FreeRDP's planar bitmap decoder has an out-of-bounds heap write when decoding RLE planar data. In libfreerdp/codec/planar.c, freerdpbitmapdecompressplanar validates the X destination coordinate nXDst against the...

CVE-2026-8326

Path traversal vulnerability in Remote Spark https://www.Remotespark.Com/ SparkView allows reading and writing arbitrary files in all directories as root. This leads to RCE. The affected component is the RDP drive redirection. Depending on implementation, the vulnerability can be exploited by an...

CVE-2026-8326

CVE-2026-8326 describes a path traversal in Remote Spark SparkView via the RDP drive redirection , enabling an unauthenticated attacker to read and write arbitrary files as root, potentially leading to remote code execution . Affected builds are listed as “before build 1127.” The CVSS 4.0 base sc...

CVE-2026-8326: Relative Path Traversal

Path traversal vulnerability in Remote Spark https://www.Remotespark.Com/ SparkView allows reading and writing arbitrary files in all directories as root. This leads to RCE. The affected component is the RDP drive redirection. Depending on implementation, the vulnerability can be exploited by an...

DEBIAN-CVE-2026-40033

FreeRDP before 3.26.0 contains a heap-buffer-overflow vulnerability in gdiCacheToSurface that allows remote attackers to write out-of-bounds heap memory. The vulnerability occurs because rectangle validation clamps coordinates to UINT16MAX but performs copy operations using unclamped cache entry...

freerdp: FreeRDP: Denial of Service via crafted audio data in RDP

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A remote attacker can exploit a sizet underflow vulnerability in the IMA-ADPCM and MS-ADPCM audio decoders by sending specially crafted audio data over the RDPSND audio channel. This underflow leads to a...

FreeRDP: FreeRDP: Information disclosure and denial of service via heap-buffer-overflow read

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. This vulnerability, a heap-buffer-overflow read, exists in the winpralignedoffsetrecalloc function. A local attacker could exploit this flaw, with user interaction, to read sensitive information from memory, leadin...
