The vulnerability in the libfreerdp/codec/h264.c file of the H.264 decompression subsystem of the RDP client FreeRDP allows a hacker to cause a service failure and expose protected information.

The vulnerability in the libfreerdp/codec/h264.c file of the H.264 decompression subsystem of the RDP client FreeRDP relates to reading data beyond the permitted range of memory. Exploiting this vulnerability can allow an attacker to cause service failures and expose sensitive information...

Vulnerability of the rpc_client_recv_fragment() function in the libfreerdp/core/gateway/rpc_client.c file of the RDP client FreeRDP, allowing a attacker to cause a service failure and execute arbitrary code.

The vulnerability of the rpcclientrecvfragment function in the libfreerdp/core/gateway/rpcclient.c file of the RDP client FreeRDP is related to buffer overflow in dynamic memory. Exploiting this vulnerability can allow an attacker to cause service failures and execute arbitrary code...

CVE-2026-69159

A flaw was found in FreeRDP, an implementation of the Remote Desktop Protocol. A malicious RDP server can exploit an out-of-bounds read vulnerability by sending a malformed planar bitmap or surface update. This causes the client's decoder to read beyond its allocated buffer, which can lead to a...

CVE-2026-63633

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A malicious Remote Desktop Protocol RDP server can exploit a heap buffer overflow vulnerability during Opus audio decoding. This occurs when the server negotiates Opus audio with a vulnerable client, causing the...

CVE-2026-55194

A flaw was found in FreeRDP. A remote attacker, specifically a malicious TS Gateway, can exploit a heap-buffer-overflow vulnerability by sending a specially crafted Remote Desktop Protocol RDP response. This occurs because the client incorrectly uses a smaller allochint value instead of the actua...

CVE-2026-63652

A flaw was found in FreeRDP. An authenticated Remote Desktop Protocol RDP client can send a specially crafted Client Audio Formats Protocol Data Unit PDU to the server. This malformed PDU can cause a double-free vulnerability in the rdpsndserverrecvformats function, leading to the server reliably...

CVE-2026-55192

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can provide a specially crafted H.264 video stream that causes the client's H.264 decoder to read beyond its allocated memory. This out-of-bounds read can lead to the disclosure of sensitive client memory or cause the...
