"According to the versions of the gstreamer1-plugins-good packages installed, the EulerOS installation on the remote host
is affected by the following vulnerabilities :

  - Integer overflow in matroskademux element in gst_matroska_demux_add_wvpk_header function which allows a
    heap overwrite while parsing matroska files. Potential for arbitrary code execution through heap
    overwrite. (CVE-2022-1920)

  - Integer overflow in avidemux element in gst_avi_demux_invert function which allows a heap overwrite while
    parsing avi files. Potential for arbitrary code execution through heap overwrite. (CVE-2022-1921)

  - DOS / potential heap overwrite in mkv demuxing using zlib decompression. Integer overflow in matroskademux
    element in gst_matroska_decompress_data function which causes a segfault, or could cause a heap overwrite,
    depending on libc and OS. Depending on the libc used, and the underlying OS capabilities, it could be just
    a segfault or a heap overwrite. If the libc uses mmap for large chunks, and the OS supports mmap, then it
    is just a segfault (because the realloc before the integer overflow will use mremap to reduce the size of
    the chunk, and it will start to write to unmapped memory). However, if using a libc implementation that
    does not use mmap, or if the OS does not support mmap while using libc, then this could result in a heap
    overwrite. (CVE-2022-1922)

  - DOS / potential heap overwrite in mkv demuxing using bzip decompression. Integer overflow in matroskademux
    element in bzip decompression function which causes a segfault, or could cause a heap overwrite, depending
    on libc and OS. Depending on the libc used, and the underlying OS capabilities, it could be just a
    segfault or a heap overwrite. If the libc uses mmap for large chunks, and the OS supports mmap, then it is
    just a segfault (because the realloc before the integer overflow will use mremap to reduce the size of the
    chunk, and it will start to write to unmapped memory). However, if using a libc implementation that does
    not use mmap, or if the OS does not support mmap while using libc, then this could result in a heap
    overwrite. (CVE-2022-1923)

  - DOS / potential heap overwrite in mkv demuxing using lzo decompression. Integer overflow in matroskademux
    element in lzo decompression function which causes a segfault, or could cause a heap overwrite, depending
    on libc and OS. Depending on the libc used, and the underlying OS capabilities, it could be just a
    segfault or a heap overwrite. If the libc uses mmap for large chunks, and the OS supports mmap, then it is
    just a segfault (because the realloc before the integer overflow will use mremap to reduce the size of the
    chunk, and it will start to write to unmapped memory). However, if using a libc implementation that does
    not use mmap, or if the OS does not support mmap while using libc, then this could result in a heap
    overwrite. (CVE-2022-1924)

  - DOS / potential heap overwrite in mkv demuxing using HEADERSTRIP decompression. Integer overflow in
    matroskaparse element in gst_matroska_decompress_data function which causes a heap overflow. Due to
    restrictions on chunk sizes in the matroskademux element, the overflow can't be triggered, however the
    matroskaparse element has no size checks. (CVE-2022-1925)

  - DOS / potential heap overwrite in qtdemux using zlib decompression. Integer overflow in qtdemux element in
    qtdemux_inflate function which causes a segfault, or could cause a heap overwrite, depending on libc and
    OS. Depending on the libc used, and the underlying OS capabilities, it could be just a segfault or a heap
    overwrite. (CVE-2022-2122)
