Debian Linux - ntfs-3g - None

Ubuntu Linux - In NTFS-3G through 2026.2.25, 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.

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21484-1 advisory.

    - CVE-2026-42616: heap buffer overflow in `cat()` of `cat.c` can lead to heap corruption in the ntfscat     binary via a       specially crafted NTFS image (bsc#1271102).
    - CVE-2026-42617: heap buffer overflow in `ntfs_ir_to_ib()` of `index.c` can lead to heap corruption in     the SUID-root       ntfs-3g binary via a specially crafted NTFS image (bsc#1271103).
    - CVE-2026-42618: heap buffer overflow in `ntfs_decompress()` of `compress.c` can lead to heap corruption     in the       SUID-root ntfs-3g binary via a specially crafted NTFS image (bsc#1271104).
    - CVE-2026-46569: heap buffer overflow in `ntfs_ib_copy_tail()` of `libntfs-3g/index.c`can lead to heap     corruption in       the SUID-root ntfs-3g binary via a specially crafted NTFS image (bsc#1271105).
    - CVE-2026-46570: heap buffer overflow in `ntfs_index_walk_down()` of `libntfs-3g/index.c` can lead to     heap corruption       in the SUID-root ntfs-3g binary via a specially crafted NTFS image (bsc#1271106).
    - CVE-2026-46571: out-of-bounds read in `ntfs_fix_file_name()` of `libntfs-3g/reparse.c` can lead to     disclosure of       confidential information from the ntfs-3g process memory when handling a specially crafted NTFS image     (bsc#1271107).
    - CVE-2026-46572: heap buffer overflow in `ntfs_ib_cut_tail()` of `libntfs-3g/index.c` can lead to heap     corruption       in the SUID-root ntfs-3g binary via a specially crafted NTFS image (bsc#1271108).
    - CVE-2026-56135: heap-based buffer overflow in `build_inherited_id()` of `libntfs-3g/security.c` can lead     to heap       corruption in the SUID-root ntfs-3g binary via a specially crafted NTFS image (bsc#1271109).
    - CVE-2026-56136: out-of-bounds read in `ntfs_ir_nill()` of `libntfs-3g/index.c` can lead to disclosure of       confidential information from the ntfs-3g process memory when handling a specially crafted NTFS image     (bsc#1271110).

    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.

    For the stable distribution (trixie), these problems have been fixed in     version 1:2022.10.3-5+deb13u2.

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

    For the detailed security status of ntfs-3g please refer to its security     tracker page at:
