The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-1b11432d52 advisory.
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients and servers that use a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch the issue. No known workarounds are available. (CVE-2024-32459)
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based based clients using /bpp:32
legacy GDI
drawing path with a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, use modern drawing paths (e.g. /rfx
or /gfx
options). The workaround requires server side support. (CVE-2024-32460)
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients using a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to integer overflow and out-of-bounds write. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, do not use /gfx
options (e.g. deactivate with /bpp:32
or /rfx
as it is on by default). (CVE-2024-32039)
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients that use a version of FreeRDP prior to 3.5.0 or 2.11.6 and have connections to servers using the NSC
codec are vulnerable to integer underflow. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, do not use the NSC codec (e.g. use -nsc
). (CVE-2024-32040)
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients that use a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, deactivate /gfx
(on by default, set /bpp
or /rfx
options instead.
(CVE-2024-32041)
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients that use a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, use /gfx
or /rfx
modes (on by default, require server side support).
(CVE-2024-32458)
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients prior to version 3.5.1 are vulnerable to out-of-bounds read. This occurs when WCHAR
string is read with twice the size it has and converted to UTF-8
, base64
decoded. The string is only used to compare against the redirection server certificate. Version 3.5.1 contains a patch for the issue. No known workarounds are available.
(CVE-2024-32662)
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients prior to version 3.5.1 are vulnerable to out-of-bounds read. Version 3.5.1 contains a patch for the issue. No known workarounds are available. (CVE-2024-32658)
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.5.1, a malicious server can crash the FreeRDP client by sending invalid huge allocation size. Version 3.5.1 contains a patch for the issue. No known workarounds are available. (CVE-2024-32660)
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients prior to version 3.5.1 are vulnerable to out-of-bounds read if ((nWidth == 0) and (nHeight == 0))
. Version 3.5.1 contains a patch for the issue. No known workarounds are available. (CVE-2024-32659)
FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients prior to version 3.5.1 are vulnerable to a possible NULL
access and crash. Version 3.5.1 contains a patch for the issue.
No known workarounds are available. (CVE-2024-32661)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
