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-2023-39350)
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-2023-39351)
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-2023-39352)
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-2023-39353)
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-2023-39354)
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-2023-39355)
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-2023-39356)
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-2023-40181)
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-2023-40186)
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-2023-40188)
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-2023-40567)
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-2023-40569)
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-2023-40589)

- An issue was discovered in FreeRDP before 2.1.1. An out-of-bounds (OOB) read vulnerability has been
detected in security_fips_decrypt in libfreerdp/core/security.c due to an uninitialized value.
(CVE-2020-13397)
- An issue was discovered in FreeRDP before 2.1.1. An out-of-bounds (OOB) write vulnerability has been
detected in crypto_rsa_common in libfreerdp/crypto/crypto.c. (CVE-2020-13398)
- In FreeRDP less than or equal to 2.1.2, an integer overflow exists due to missing input sanitation in
rdpegfx channel. All FreeRDP clients are affected. The input rectangles from the server are not checked
against local surface coordinates and blindly accepted. A malicious server can send data that will crash
the client later on (invalid length arguments to a `memcpy`) This has been fixed in 2.2.0. As a
workaround, stop using command line arguments /gfx, /gfx-h264 and /network:auto (CVE-2020-15103)
- In FreeRDP before version 2.1.2, there is an out of bounds read in TrioParse. Logging might bypass string
length checks due to an integer overflow. This is fixed in version 2.1.2. (CVE-2020-4030)
- 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-2020-4031)
- In FreeRDP before version 2.1.2, there is an integer casting vulnerability in update_recv_secondary_order.
All clients with +glyph-cache /relax-order-checks are affected. This is fixed in version 2.1.2.
(CVE-2020-4032)
- In FreeRDP before version 2.1.2, there is an out of bounds read in RLEDECOMPRESS. All FreeRDP based
clients with sessions with color depth < 32 are affected. This is fixed in version 2.1.2. (CVE-2020-4033)
- 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-2023-39350)
- 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-2023-39351)
- 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-2023-39352)
- 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-2023-39353)
- 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-2023-39354)
- 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-2023-39355)
- 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-2023-39356)
- 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-2023-40181)
- 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-2023-40186)
- 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-2023-40188)
- 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-2023-40567)
- 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-2023-40569)
- 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-2023-40589)
