Tuxera: >> Ntfs-3g >> 2015.3.14 Security Vulnerabilities
In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_index_walk_down() in libntfs-3g/index.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by reading the special crafted file metadata.

In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_ib_copy_tail(), in libntfs-3g/index.c, that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by extending a directory, e.g., by creating a file.

In NTFS-3G before 2026.7.7, a out-of-bounds read exists in ntfs_fix_file_name() in libntfs-3g/reparse.c that allows an attacker to read possibly confidential information in ntfs-3g process memory by crafting a malicious NTFS image. The out-of-bounds read is triggered by a readlink on a corrupted file.

In NTFS-3G through 2026.2.25, a heap-based buffer overflow exists in the function build_inherited_id() in libntfs-3g/security.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by creating a file in a crafted directory.

In NTFS-3G through 2026.2.25, an out-of-bounds read exists in ntfs_ir_nill() in libntfs-3g/index.c that allows an attacker to read possibly confidential information in an ntfs-3g process by crafting a malicious NTFS image. This read operation is triggered by creation of a file with a crafted name.

A buffer overflow was discovered in NTFS-3G before 2022.10.3. Crafted metadata in an NTFS image can cause code execution. A local attacker can exploit this if the ntfs-3g binary is setuid root. A physically proximate attacker can exploit this if NTFS-3G software is configured to execute upon attachment of an external storage device.
