CVE-2023-40187 1 Freerdp 1 Freerdp 2024-01-12 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions of the 3.x beta branch are subject to a Use-After-Free issue in the `avc420_ensure_buffer` and `avc444_ensure_buffer` functions. If the value of `piDstSize[x]` is 0, `ppYUVDstData[x]` will be freed. However, in this case `ppYUVDstData[x]` will not have been updated which leads to a Use-After-Free vulnerability. This issue has been addressed in version 3.0.0-beta3. Users of the 3.x beta releases are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2023-39355 2 Debian, Freerdp 2 Debian Linux, Freerdp 2024-01-12 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Versions of FreeRDP on the 3.x release branch before beta3 are subject to a Use-After-Free in processing `RDPGFX_CMDID_RESETGRAPHICS` packets. If `context->maxPlaneSize` is 0, `context->planesBuffer` will be freed. However, without updating `context->planesBuffer`, this leads to a Use-After-Free exploit vector. In most environments this should only result in a crash. This issue has been addressed in version 3.0.0-beta3 and users of the beta 3.x releases are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2023-39352 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an invalid offset validation leading to Out Of Bound Write. This can be triggered when the values `rect->left` and `rect->top` are exactly equal to `surface->width` and `surface->height`. eg. `rect->left` == `surface->width` && `rect->top` == `surface->height`. In practice this should cause a crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2023-39353 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 9.1 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to a missing offset validation leading to Out Of Bound Read. In the `libfreerdp/codec/rfx.c` file there is no offset validation in `tile->quantIdxY`, `tile->quantIdxCb`, and `tile->quantIdxCr`. As a result crafted input can lead to an out of bounds read access which in turn will cause a crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2023-39356 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 9.1 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. In affected versions a missing offset validation may lead to an Out Of Bound Read in the function `gdi_multi_opaque_rect`. In particular there is no code to validate if the value `multi_opaque_rect->numRectangles` is less than 45. Looping through `multi_opaque_rect->`numRectangles without proper boundary checks can lead to Out-of-Bounds Read errors which will likely lead to a crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2023-40181 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 9.1 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Integer-Underflow leading to Out-Of-Bound Read in the `zgfx_decompress_segment` function. In the context of `CopyMemory`, it's possible to read data beyond the transmitted packet range and likely cause a crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.
CVE-2023-40186 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an IntegerOverflow leading to Out-Of-Bound Write Vulnerability in the `gdi_CreateSurface` function. This issue affects FreeRDP based clients only. FreeRDP proxies are not affected as image decoding is not done by a proxy. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.
CVE-2023-40575 1 Freerdp 1 Freerdp 2024-01-12 N/A 9.1 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Read in the `general_YUV444ToRGB_8u_P3AC4R_BGRX` function. This issue is likely down to insufficient data for the `pSrc` variable and results in crashes. This issue has been addressed in version 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.
CVE-2023-40574 1 Freerdp 1 Freerdp 2024-01-12 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Write in the `writePixelBGRX` function. This issue is likely down to incorrect calculations of the `nHeight` and `srcStep` variables. This issue has been addressed in version 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.
CVE-2023-40569 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Write in the `progressive_decompress` function. This issue is likely down to incorrect calculations of the `nXSrc` and `nYSrc` variables. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. there are no known workarounds for this vulnerability.
CVE-2023-40567 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Write in the `clear_decompress_bands_data` function in which there is no offset validation. Abuse of this vulnerability may lead to an out of bounds write. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. there are no known workarounds for this vulnerability.
CVE-2023-40188 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 9.1 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Read in the `general_LumaToYUV444` function. This Out-Of-Bounds Read occurs because processing is done on the `in` variable without checking if it contains data of sufficient length. Insufficient data for the `in` variable may cause errors or crashes. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.
CVE-2022-24883 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2023-11-17 6.8 MEDIUM 9.8 CRITICAL
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP). Prior to version 2.7.0, server side authentication against a `SAM` file might be successful for invalid credentials if the server has configured an invalid `SAM` file path. FreeRDP based clients are not affected. RDP server implementations using FreeRDP to authenticate against a `SAM` file are affected. Version 2.7.0 contains a fix for this issue. As a workaround, use custom authentication via `HashCallback` and/or ensure the `SAM` database path configured is valid and the application has file handles left.
