freerdp: FreeRDP: Arbitrary code execution and denial of service via malicious server

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A malicious server can exploit a use-after-free vulnerability by enticing a client to connect to it. This can lead to a client-side crash, resulting in a Denial of Service DoS, and potentially allow for arbitrary...

freerdp: FreeRDP: Denial of Service and potential code execution via use-after-free vulnerability

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A malicious server can exploit this vulnerability when a client connects to it. Specifically, offscreen bitmap deletion can lead to a use-after-free UAF condition, where the client attempts to use memory that has...

SUSE CVE-2026-23531

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, in ClearCodec, when glyphData is present, cleardecompress calls freerdpimagecopynooverlap without validating the destination rectangle, allowing an out-of-bounds read/write via crafted RDPGFX surface updates...

SUSE CVE-2026-23533

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, a client-side heap buffer overflow occurs in the RDPGFX ClearCodec decode path when maliciously crafted residual data causes out-of-bounds writes during color output. A malicious server can trigger a...

SUSE CVE-2026-23883

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, xfPointerNew frees cursorPixels on failure, then pointerfree calls xfPointerFree and frees it again, triggering ASan UAF. A malicious server can trigger a client-side use after free, causing a crash DoS and...

The vulnerability of the ndr_read_uint8Array() function in the RDP client of FreeRDP, allowing a hacker to execute arbitrary code or cause a service failure.

The vulnerability of the ndrreaduint8Array function in the RDP client FreeRDP is related to writing beyond the buffer boundaries. Exploiting this vulnerability could allow a malicious actor to execute arbitrary code or cause service failures remotely...

The vulnerability of the create_irp_thread() function in the RDP client of FreeRDP, which allows a hacker to execute arbitrary code or cause a service failure.

The vulnerability of the createirpthread function in the RDP client of FreeRDP is related to synchronization errors when using a shared resource. Exploiting this vulnerability allows an attacker to execute arbitrary code or cause service failures...

The vulnerability of the RDP client FreeRDP, related to the execution of operations beyond the buffer boundaries in memory, allows a hacker to trigger a service failure.

The vulnerability of the RDP client FreeRDP is related to the escape of operations beyond the buffer in memory due to incorrect encoding based on the Base64 standard. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...
