Debian Bug     : 1011770

Several vulnerabilities were discovered in NTFS-3G, a read-write NTFS
driver for FUSE. A local user can take advantage of these flaws for
local root privilege escalation.

CVE-2022-30783

    An invalid return code in fuse_kern_mount enables intercepting of
    libfuse-lite protocol traffic between NTFS-3G and the kernel when
    using libfuse-lite.

CVE-2022-30784

    A crafted NTFS image can cause heap exhaustion in
    ntfs_get_attribute_value.

CVE-2022-30785

    A file handle created in fuse_lib_opendir, and later used in
    fuse_lib_readdir, enables arbitrary memory read and write
    operations when using libfuse-lite.

CVE-2022-30786

    A crafted NTFS image can cause a heap-based buffer overflow in
    ntfs_names_full_collate.

CVE-2022-30787

    An integer underflow in fuse_lib_readdir enables arbitrary memory
    read operations when using libfuse-lite.

CVE-2022-30788

    A crafted NTFS image can cause a heap-based buffer overflow in
    ntfs_mft_rec_alloc.

CVE-2022-30789

     A crafted NTFS image can cause a heap-based buffer overflow in
     ntfs_check_log_client_array.

For Debian 9 stretch, these problems have been fixed in version
1:2016.2.22AR.1+dfsg-1+deb9u3.

We recommend that you upgrade your ntfs-3g packages.
