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

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 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 3.23.0, 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 freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Clients and servers that use versions of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read vulnerabilities. Versions 3.5.0 and 2.11.6 address this issue. There are no known workarounds available...

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 freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Clients that use versions of FreeRDP before 3.5.0 or 2.11.6 are vulnerable to integer overflows and out-of-bounds writes. Versions 3.5.0 and 2.11.6 address this issue. As a workaround, do not use /gfx options for example, deactivate...

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 3.24.0, 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, 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 freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Clients that use FreeRDP versions prior to 3.5.0 or 2.11.6 and have connections to servers using the NSC codec are vulnerable to integer underflow. Versions 3.5.0 and 2.11.6 address this issue. As a workaround, do not use the NSC...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Clients that use versions of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read vulnerabilities. Versions 3.5.0 and 2.11.6 address this issue. As a workaround, deactivate /gfx which is enabled by default; instead,...

Astra Linux – Vulnerability in freerdp3, freerdp2

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 a use-after-free situation in the urbwritecompletion function. This...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol RDP, released under the Apache license. This issue only affects clients. An integer underflow can lead to a Denial of Service DOS vulnerability, for example, an abort due to WINPRASSERT with default compilation flags. When an...

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...

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...

The vulnerability of the tls_match_hostname() function in the libfreerdp/crypto/tls.c file of the RDP client FreeRDP allows a attacker to replace the RDP server.

The vulnerability of the tlsmatchhostname function in the libfreerdp/crypto/tls.c file of the RDP client FreeRDP is related to errors in the certificate authentication process. Exploiting this vulnerability could allow an attacker to remotely replace the RDP server...
