CVE-2023-40576 1 Freerdp 1 Freerdp 2024-01-12 N/A 7.5 HIGH
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 `RleDecompress` function. This Out-Of-Bounds Read occurs because FreeRDP processes the `pbSrcBuffer` variable without checking if it contains data of sufficient length. Insufficient data in the `pbSrcBuffer` variable may cause errors or 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-2023-40589 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 7.5 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. In affected versions there is a Global-Buffer-Overflow in the ncrush_decompress function. Feeding crafted input into this function can trigger the overflow which has only been shown to 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-2023-39350 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 7.5 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. This issue affects Clients only. Integer underflow leading to DOS (e.g. abort due to `WINPR_ASSERT` with default compilation flags). When an insufficient blockLen is provided, and proper length validation is not performed, an Integer Underflow occurs, leading to a Denial of Service (DOS) vulnerability. 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-2023-39351 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 7.5 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions of FreeRDP are subject to a Null Pointer Dereference leading a crash in the RemoteFX (rfx) handling. Inside the `rfx_process_message_tileset` function, the program allocates tiles using `rfx_allocate_tiles` for the number of numTiles. If the initialization process of tiles is not completed for various reasons, tiles will have a NULL pointer. Which may be accessed in further processing and would cause a program 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-2023-39354 3 Debian, Fedoraproject, Freerdp 3 Debian Linux, Fedora, Freerdp 2024-01-12 N/A 7.5 HIGH
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 `nsc_rle_decompress_data` function. The Out-Of-Bounds Read occurs because it processes `context->Planes` without checking if it contains data of sufficient length. Should an attacker be able to leverage this vulnerability they may be able to 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-2022-39282 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2023-11-17 N/A 7.5 HIGH
FreeRDP is a free remote desktop protocol library and clients. FreeRDP based clients on unix systems using `/parallel` command line switch might read uninitialized data and send it to the server the client is currently connected to. FreeRDP based server implementations are not affected. Please upgrade to 2.8.1 where this issue is patched. If unable to upgrade, do not use parallel port redirection (`/parallel` command line switch) as a workaround.
CVE-2021-41160 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2023-11-17 6.8 MEDIUM 8.8 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. In affected versions a malicious server might trigger out of bound writes in a connected client. Connections using GDI or SurfaceCommands to send graphics updates to the client might send `0` width/height or out of bound rectangles to trigger out of bound writes. With `0` width or heigth the memory allocation will be `0` but the missing bounds checks allow writing to the pointer at this (not allocated) region. This issue has been patched in FreeRDP 2.4.1.
CVE-2022-39283 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2023-11-17 N/A 7.5 HIGH
FreeRDP is a free remote desktop protocol library and clients. All FreeRDP based clients when using the `/video` command line switch might read uninitialized data, decode it as audio/video and display the result. FreeRDP based server implementations are not affected. This issue has been patched in version 2.8.1. If you cannot upgrade do not use the `/video` switch.
CVE-2017-2835 2 Debian, Freerdp 2 Debian Linux, Freerdp 2022-06-07 6.8 MEDIUM 8.1 HIGH
An exploitable code execution vulnerability exists in the RDP receive functionality of FreeRDP 2.0.0-beta1+android11. A specially crafted server response can cause an out-of-bounds write resulting in an exploitable condition. An attacker can compromise the server or use a man in the middle to trigger this vulnerability.
CVE-2017-2834 2 Debian, Freerdp 2 Debian Linux, Freerdp 2022-06-07 6.8 MEDIUM 7.0 HIGH
An exploitable code execution vulnerability exists in the authentication functionality of FreeRDP 2.0.0-beta1+android11. A specially crafted server response can cause an out-of-bounds write resulting in an exploitable condition. An attacker can compromise the server or use a man in the middle attack to trigger this vulnerability.
CVE-2020-4031 4 Canonical, Fedoraproject, Freerdp and 1 more 4 Ubuntu Linux, Fedora, Freerdp and 1 more 2022-06-01 4.3 MEDIUM 7.5 HIGH
In FreeRDP before version 2.1.2, there is a use-after-free in gdi_SelectObject. All FreeRDP clients using compatibility mode with /relax-order-checks are affected. This is fixed in version 2.1.2.
CVE-2022-24882 1 Freerdp 1 Freerdp 2022-05-11 5.0 MEDIUM 7.5 HIGH
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 and empty password value. This issue affects FreeRDP based RDP Server implementations. RDP clients are not affected. The vulnerability is patched in FreeRDP 2.7.0. There are currently no known workarounds.
CVE-2021-41159 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2021-11-30 6.8 MEDIUM 8.8 HIGH
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. All FreeRDP clients prior to version 2.4.1 using gateway connections (`/gt:rpc`) fail to validate input data. A malicious gateway might allow client memory to be written out of bounds. This issue has been resolved in version 2.4.1. If you are unable to update then use `/gt:http` rather than /gt:rdp connections if possible or use a direct connection without a gateway.
CVE-2019-17177 2 Freerdp, Opensuse 2 Freerdp, Leap 2021-07-21 5.0 MEDIUM 7.5 HIGH
libfreerdp/codec/region.c in FreeRDP through 1.1.x and 2.x through 2.0.0-rc4 has memory leaks because a supplied realloc pointer (i.e., the first argument to realloc) is also used for a realloc return value.
CVE-2019-17178 3 Freerdp, Lodev, Opensuse 3 Freerdp, Lodepng, Leap 2021-07-21 5.0 MEDIUM 7.5 HIGH
