FreeRDP: FreeRDP: HTTP Proxy Request Injection via Redirection

A flaw was found in FreeRDP. A malicious or compromised Remote Desktop Protocol RDP server can exploit this vulnerability to inject arbitrary headers or requests into an HTTP proxy CONNECT request. This occurs because FreeRDP does not properly validate control characters in the server-controlled...

FreeRDP: FreeRDP: Arbitrary code execution via malicious RDP files

A flaw in FreeRDP's file parser incorrectly treats lines starting with a forward slash / as command-line options. If a victim opens a maliciously crafted .rdp file, an attacker can silently inject CLI flags to execute arbitrary code, expose local filesystems, or bypass certificate validation...

FreeRDP: FreeRDP: Denial of Service via crafted WindowIcon async message

A flaw was found in FreeRDP. A malicious or compromised Remote Desktop Protocol RDP server can exploit a heap use-after-free vulnerability when a client connects with asynchronous updates enabled. By sending a specially crafted Window Alternate Secondary Order message, the server can trigger memo...

A flaw was found in FreeRDP. A malicious or compromised Remote Desktop Protocol RDP server can exploit this vulnerability to inject arbitrary headers or requests into an HTTP proxy CONNECT request. This occurs because FreeRDP does not properly validate control characters in the server-controlled...

FreeRDP: FreeRDP: Remote code execution or denial of service via audio input integer overflow

A flaw was found in FreeRDP, an open-source implementation of the Remote Desktop Protocol RDP. This vulnerability, an integer overflow in the audio input redirection channel, allows a remote attacker to supply a malicious FramesPerPacket value. This can lead to a heap-based buffer overflow,...

FreeRDP: FreeRDP: Double-free vulnerability via crafted .rdp file leading to potential remote code execution

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A double-free vulnerability exists when a FreeRDP client processes a specially crafted .rdp connection file. An attacker could convince a victim to open a malicious .rdp file, leading to a size-controlled...

Important: Red Hat Security Advisory: freerdp security update

An update for freerdp is now available for Red Hat Enterprise Linux 10.0 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available fo...

FreeRDP: FreeRDP: Remote code execution or denial of service via heap-based buffer overflow

A heap-based buffer overflow in FreeRDP's cryptorsacommon allows an unauthenticated remote attacker to trigger a denial of service or potential remote code execution. By sending a crafted ciphertext during RDP Standard Security key establishment, the attacker can force a data write before the siz...

ROS-20260824-73-0009

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...

ROS-20260824-73-0010

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...
