- More information:
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.
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.
A crafted NTFS image can cause heap exhaustion in ntfs_get_attribute_value.
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.
A crafted NTFS image can cause a heap-based buffer overflow in ntfs_names_full_collate.
An integer underflow in fuse_lib_readdir enables arbitrary memory read operations when using libfuse-lite.
A crafted NTFS image can cause a heap-based buffer overflow in ntfs_mft_rec_alloc.
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.
