Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfrailserverlocalmovesize dereferenced a freed xfAppWindow pointer because xfrailgetwindow returned an unprotected pointer from the railWindows hash table. This could allow the main thread to delete the wind...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, the ecamencodercompressh264 function relied on server-controlled dimensions and did not validate the source buffer size, resulting in a out-of-bounds read in swsscale. This vulnerability has been fixed in...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a buffer overread could occur in the freerdpimagecopyfromicondata function libfreerdp/codec/color.c, due to malicious RDP window icon TSICONINFO data. This bug could be exploited over the network when a clie...

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfcliprdrprovidedata passed the freed pDstData to XChangeProperty. This was because the cliprdr channel thread called xfcliprdrserverformatdataresponse, which converted and used the clipboard data without...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, a capture thread sent sample responses using a freed channel callback after a device channel was closed, resulting in a use of memory after deallocation in ecamchannelwrite. This vulnerability has been fixed...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, a double-free vulnerability in the functions kerberosAcceptSecurityContext and kerberosInitializeSecurityContextA located in WinPR, winpr/libwinpr/sspi/Kerberos/kerberos.c could cause crashes in any FreeRDP...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.1, a memory access violation occurred in irpthreadfunc because the IRP was freed by irp-Complete, and then accessed again during the error handling path. This vulnerability has been fixed in version 3.20.1...

CVE-2026-67290

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can send specially crafted media data to a connected client. This malformed data can trigger a heap out-of-bounds read vulnerability within the TSMF FFmpeg decoder, leading to the client application crashing. This can...

CVE-2026-67296

A flaw was found in FreeRDP. A remote attacker can exploit a vulnerability in the Remote Desktop Protocol RDP Enhanced Input RDPEI server channel handler. By sending a malicious RDPEI message with an oversized declared body length, the attacker can force the server to allocate excessive memory,...

CVE-2026-67304

A null pointer dereference flaw in FreeRDP allows a remote attacker to cause a denial of service DoS via specially crafted smartcard requests. If reader-state decoding fails, the system attempts to free uninitialized states during cleanup, resulting in a process crash. Mitigation To mitigate this...

CVE-2026-67303

A flaw was found in FreeRDP. When serial device redirection is active, a malicious server can send a crafted device control request. If this request specifies an unsupported operation with a non-zero output buffer, it can cause the FreeRDP client process to unexpectedly terminate. This leads to a...

CVE-2026-68579

A flaw was found in FreeRDP. A heap-based buffer overflow exists in the Windows clipboard client's CliprdrStreamRead function. A malicious or compromised Remote Desktop Protocol RDP server can send an oversized clipboard file contents response. When a user pastes this content, it causes an...

CVE-2026-67291

A heap out-of-bounds read vulnerability in FreeRDP allows an unauthenticated, malicious RDP server to cause a Denial of Service. By sending a specially crafted glyph fragment update, the server forces the client to read beyond its allocated memory, crashing the application. Mitigation To mitigate...

CVE-2026-67297

A vulnerability in FreeRDP allows a malicious RD Gateway to bypass client-side size limits by sending oversized chunked HTTP responses. This exhausts the client's memory, resulting in a Denial of Service DoS. Mitigation To mitigate this issue, FreeRDP clients should only connect to trusted Remote...

CVE-2026-67301

A flaw was found in FreeRDP. When the async-update feature is enabled, a malicious or compromised Remote Desktop Protocol RDP server can send specially crafted update orders. This can lead to an out-of-bounds read, potentially exposing sensitive information or causing the client application to...

FreeRDP: FreeRDP: Remote code execution via heap out-of-bounds write in RemoteFX decoding

A flaw was found in FreeRDP. FreeRDP clients using the non-default /cache:codec:rfx option are vulnerable to a heap out-of-bounds write. A malicious Remote Desktop Protocol RDP server can exploit this by manipulating desktop stride and height values during RemoteFX decoding for Cache Bitmap V3...
