"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0177 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-6349:
    A heap overflow vulnerability exists in libvpx -Encoding a frame that has larger dimensions than the
    originally configured size with VP9 may result in a heap overflow in libvpx.
    We recommend upgrading to version 1.13.1 or above

    CVE-2024-5197:
    There exists interger overflows in libvpx in versions prior to 1.14.1.Calling vpx_img_alloc()with a
    large value of the d_w, d_h, or alignparameter may result in integer overflows in the calculations of
    buffer sizes and offsets and some fields of the returned vpx_image_tstruct may be invalid.Calling
    vpx_img_wrap()with a large value of the d_w, d_h, or stride_alignparameter may result in integer
    overflows in the calculations of buffer sizes and offsets and some fields of the returned
    vpx_image_tstruct may be invalid. We recommend upgrading to version 1.14.1 or beyond
