Affected: AlmaLinux:9: freerdp, AlmaLinux:9: freerdp-devel, AlmaLinux:9: freerdp-libs, AlmaLinux:9: libwinpr, AlmaLinux:9: libwinpr-devel

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. The xfreerdp client can connect to RDP servers such as Microsoft Windows machines, xrdp, and VirtualBox.

Security Fix(es):

* freerdp: Incorrect offset calculation leading to DOS (CVE-2023-39350) * freerdp: Null Pointer Dereference leading DOS in RemoteFX (CVE-2023-39351) * freerdp: invalid offset validation leading to Out Of Bound Write (CVE-2023-39352) * freerdp: missing offset validation leading to Out-of-Bounds Read in gdi_multi_opaque_rect (CVE-2023-39356) * freerdp: Integer overflow leading to out-of-bound write vulnerability in gdi_CreateSurface (CVE-2023-40186) * freerdp: Out-of-bounds write in clear_decompress_bands_data (CVE-2023-40567) * freerdp: Out-of-bounds write in the `progressive_decompress` function due to incorrect calculations (CVE-2023-40569) * freerdp: buffer overflow in ncrush_decompress causes crash with crafted input (CVE-2023-40589) * freerdp: missing offset validation leading to Out Of Bound Read (CVE-2023-39353) * freerdp: Out-Of-Bounds Read in nsc_rle_decompress_data (CVE-2023-39354) * freerdp: integer-Underflow leading to Out-Of-Bound Read in zgfx_decompress_segment (CVE-2023-40181) * freerdp: Out-of-bounds read in general_LumaToYUV444 (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 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.

OESA-2023-1656 — freerdp security update

Affected: openEuler:20.03-LTS-SP1: freerdp, openEuler:20.03-LTS-SP3: freerdp, openEuler:22.03-LTS: freerdp, openEuler:22.03-LTS-SP1: freerdp, openEuler:22.03-LTS-SP2: freerdp

FreeRDP is a client implementation of the Remote Desktop Protocol (RDP) that follows Microsoft's open specifications. This package provides the client applications xfreerdp and wlfreerdp. Security Fix(es): 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-…
