Heap-based Buffer Overflow em Tuxera Ntfs-3g

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.

CVE-2026-46572 Alta · 7.4 CWE-122 07/10/2026

Heap-based Buffer Overflow em Tuxera Ntfs-3g

In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_ib_cut_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 creating a file in a specially crafted directory.

CVE-2026-46571 Média · 5.5 CWE-125 07/10/2026

Out-of-bounds Read em Tuxera Ntfs-3g

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.

CVE-2026-46569 Alta · 7.7 CWE-787 07/10/2026

Out-of-bounds Write em Tuxera Ntfs-3g

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.

CVE-2026-42618 Alta · 7.1 CWE-122 07/10/2026

Heap-based Buffer Overflow em Tuxera Ntfs-3g

In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_decompress() in compress.c that allows an attacker to corrupt one byte of 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.
