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, 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 3.24.2, 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

FreeRDP is a free implementation of the Remote Desktop Protocol. Versions prior to 3.25.0 have a flaw in the path traversal filter in channels/drive/client/drivefile.c. The containsDotDot function detects ../ and .. in the path, but misses .. when it’s the last component without a trailing...

Astra Linux – Vulnerability in freerdp3, freerdp2

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 3.24.2, in the resizevbarentry function in libfreerdp/codec/clear.c, vBarEntry-size was updated to vBarEntry-count before the winpralignedrecalloc call. If the realloc call fails, the size is inflated, and the pixel...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, a underflow of a sizet variable in the IMA-ADPCM and MS-ADPCM audio decoders led to a heap-buffer-overflow issue through the RDPSND audio channel. In libfreerdp/codec/dsp.c, the IMA-ADPCM and MS-ADPCM decode...

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 3.20.1, the NDR array reader in RDPEAR did not perform bounds checking on the number of on-wire elements, and could write beyond the heap buffer allocated from hints, resulting in a heap buffer overflow in...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol RDP. In versions prior to 2.7.0, NT LAN Manager NTLM authentication does not properly abort when someone provides an empty password value. This issue affects FreeRDP-based RDP Server implementations. RDP clients are not affected. The...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.1, a malicious RDP server could trigger a heap-buffer-overflow write in the FreeRDP client when processing Audio Input AUDIN format lists. The audinprocessformats function reuses the callback-formatscount...

Astra Linux – Vulnerability in freerdp2

FreeRDP is a free remote desktop protocol library and client. All FreeRDP-based clients that use the /video command-line switch may read uninitialized data, interpret it as audio/video, and display the result. Server implementations based on FreeRDP are not affected by this issue. This issue has...

Astra Linux – Vulnerability in freerdp3, freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, audinserverrecvformats freed an incorrect number of audio formats upon parse failure i + i, resulting in out-of-bounds access in audioformatsfree. This vulnerability has been fixed in version 3.22.0...

Astra Linux – Vulnerability in freerdp3, freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, a client-side heap buffer overflow occurred in the gdiSurfaceToSurface path of the FreeRDP client due to a mismatch between destination rectangle clamping and the actual copy size. A malicious server can...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, FastGlyph parsing relied on cbData/remaining length, and never validated against the minimum size implied by cx/cy. A malicious server could trigger a client-side global buffer overflow, resulting in a crash...

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 =...

CVE-2021-41160

CVE-2021-41160 FreeRDP 是一个自由实现的远程桌面协议（RDP），基于 Apache 许可证发布。在受影响版本中，恶意服务器可能触发已连接客户端的越界写入。使用 GDI 或 SurfaceCommands 向客户端发送图形更新的连接，可能会发送宽度/高度为 0 或越界的矩形，从而触发越界写入。当宽度或高度为 0 时，内存分配为 0，但缺失的边界检查允许写入指向该（未分配）区域的指针。此问题已在 FreeRDP 2.4.1 中修复。 认证| 复杂度| 攻击向量 ---|---|--- 无| 中| 网络 机密性| 完整性| 可用性 ---|---|--- 部分| 部分| ...
