CVE-2026-67289

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...

Linux Distros Unpatched Vulnerability : CVE-2026-72746

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - FreeRDP before 3.30.0 contains a server-side authentication bypass in the RDSTLS handshake. When a server is configured with RdstlsSecurity = TRUE, the handshak...

PT-2026-70159

FreeRDP before 3.30.0 contains a server-side authentication bypass in the RDSTLS handshake. When a server is configured with RdstlsSecurity = TRUE, the handshake dispatches inbound PDUs based solely on the attacker-supplied wire pduType without verifying that the received PDU is the one required ...

PT-2026-70158

FreeRDP before 3.30.0 contains an out-of-bounds vulnerability in kerberos DecryptMessage winpr/libwinpr/sspi/Kerberos/kerberos.c. The 16-bit EC extra count field of a peer-supplied GSS Wrap token RFC 4121 is used directly in pointer arithmetic to locate the encrypted regions without being...

PT-2026-70897

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.30.0, FreeRDP server-side RDSTLS in libfreerdp/core/rdstls.c accepts an attacker-supplied RDSTLS TYPE CAPABILITIES PDU while rdstls server authenticate is waiting for RDSTLS TYPE AUTHREQ, leaving resultCode at RDSTLS RESU...

PT-2026-70898

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.30.0, FreeRDP's winpr/libwinpr/sspi/Kerberos/kerberos.c kerberos DecryptMessage function fails to bound the peer-controlled GSS Wrap-token EC field before using it with RRC in IOV pointer offsets, allowing a malicious RDP...

Astra Linux – Vulnerability in freerdp3

FreeRDP before version 3.22.0 contains a use-after-free vulnerability in the dvcmanchannelclose and dvcmancallonreceive functions, due to improper synchronization of channel callback access. A malicious RDP server can trigger a race condition by sending DYNVCDATA and DYNVCCLOSE messages...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, the sdlPointerNew function freed memory upon failure. However, the pointerfree function would call sdlPointerFree, which further freed the memory, leading to a Universal Address Forgery UAF vulnerability. Th...

Astra Linux – Vulnerability in freerdp3

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

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, in ClearCodec, when glyphData was present, cleardecompress called freerdpimagecopynooverlap without validating the destination rectangle. This allowed out-of-bounds read/writing through crafted RDPGFX surfac...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in the persistentcachereadentryv3 function in libfreerdp/cache/persistent.c, persistent-bmpSize was updated before winpralignedrecalloc. If realloc fails, bmpSize is inflated while bmpData points to the old...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, there was a buffer overflow vulnerability in freerdpbitmapdecompressplanar when SrcSize was 0. The function dereferences srcp which points to pSrcData without first verifying that SrcSize is greater than or...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, pixel data from adjacent heap memory was rendered to the screen, potentially exposing sensitive data to attackers. This issue has been fixed in version 3.24.2...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, the RDPSND async playback thread could process queued PDUs after the channel was closed and its internal state was freed, resulting in a use after free in rdpsndtreatwave. This vulnerability has been fixed i...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.1, a global-buffer-overflow issue was observed during FreeRDP’s Base64 decoding process. The root cause appears to be implementation-defined char signedness: on Arm/AArch64 builds, plain char values are treated...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, the progressivedecompresstileupgrade function detected mismatches using progressiverfxquantcmpequal, but only emitted a WLogWARN message; execution continued. The wrapped value 247 was used as a shift...

Astra Linux – Vulnerability in freerdp3
