The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.
freerdp: Integer Overflow leading to Heap Overflow in freerdp_bitmap_planar_context_reset (CVE-2024-22211)
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)
Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
