Description

The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1609-1 advisory.

- 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 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
