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, 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 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 3.24.2, there was a heap-buffer-overflow vulnerability at 24 bytes before the allocation, in the function winpralignedoffsetrecalloc. 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 3.23.0, xfAppUpdateWindowFromSurface read data from a freed xfAppWindow, because the RDPGFX DVC thread obtained a bare pointer via xfrailgetwindow without any lifetime protection. Meanwhile, the main thread could...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, asynchronous bulk transfer operations could cause a freed channel callback to be used after the URBDRC channel was closed, resulting in an use-after-free condition in the urbwritecompletion function. This...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, division by zero occurred in MS-ADPCM and IMA-ADPCM decoders when nBlockAlign was 0, resulting in a crash. In libfreerdp/codec/dsp.c, both ADPCM decoders use size % blocksize, where blocksize =...

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 3.23.0, 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...

Astra Linux – Vulnerability in freerdp3

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 3.24.2, 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...

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-2026-67297

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-2026-67298

A flaw was found in FreeRDP. A remote attacker, by sending a specially crafted Remote Desktop Protocol RDP packet, could trigger a heap buffer overflow in the server-side RAIL channel handler. This vulnerability, caused by an integer underflow, allows the attacker to corrupt memory and crash the...

UBUNTU-CVE-2026-68580

FreeRDP before 3.29.0 contains integer overflow vulnerabilities in the audio input redirection channel audin across ALSA, sndio, WinMM, and OpenSL ES backends that fail to validate the FramesPerPacket parameter from RDP servers. Attackers can supply a malicious FramesPerPacket value causing...
