The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6749-1 advisory.

    It was discovered that FreeRDP incorrectly handled certain context resets. If a user were tricked into     connecting to a malicious server, a remote attacker could use this issue to cause FreeRDP to crash,     resulting in a denial of service, or possibly execute arbitrary code. (CVE-2024-22211)

    Evgeny Legerov discovered that FreeRDP incorrectly handled certain memory operations. If a user were     tricked into connecting to a malicious server, a remote attacker could use this issue to cause FreeRDP to     crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2024-32039,     CVE-2024-32040)

According to the versions of the freerdp packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    FreeRDP is a set of free and open source remote desktop protocol library and clients. In affected versions     an integer overflow in `freerdp_bitmap_planar_context_reset` leads to heap-buffer overflow. This affects     FreeRDP based clients. FreeRDP based server implementations and proxy are not affected. A malicious server     could prepare a `RDPGFX_RESET_GRAPHICS_PDU` to allocate too small buffers, possibly triggering later out     of bound read/write. Data extraction over network is not possible, the buffers are used to display an     image. This issue has been addressed in version 2.11.5 and 3.2.0. Users are advised to upgrade. there are     no know workarounds for this vulnerability.(CVE-2024-22211)
