OESA-2021-1365

NTFS-3G is a stable, open source, GPL licensed, POSIX, read/write NTFS driver for Linux and many other operating systems. It provides safe handling of the Windows XP, Windows Server 2003, Windows 2000, Windows Vista, Windows Server 2008 and Windows 7 NTFS file systems.

Security Fix(es):

In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function ntfsgetattributevalue, a heap buffer overflow can occur allowing for memory disclosure or denial of service. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the "bytesinuse" field should be less than the "bytesallocated" field. When it is not, the parsing of the records proceeds into the wild.(CVE-2021-33285)

A crafted NTFS image can cause an out-of-bounds read in ntfsielookup in NTFS-3G < 2021.8.22.(CVE-2021-39252)

A crafted NTFS image can cause an out-of-bounds access in ntfsinodesyncstandardinformation in NTFS-3G < 2021.8.22.(CVE-2021-39260)

A crafted NTFS image can trigger an out-of-bounds access, caused by an unsanitized attribute length in ntfsinodelookupbyname, in NTFS-3G < 2021.8.22.(CVE-2021-39259)

In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode is loaded in the function ntfsinodereal_open, a heap buffer overflow can occur allowing for code execution and escalation of privileges.(CVE-2021-35268)

A crafted NTFS image can cause a heap-based buffer overflow in ntfsinodelookupbyname in NTFS-3G < 2021.8.22.(CVE-2021-39256)

A crafted NTFS image can cause an out-of-bounds read in ntfsrunlistsmerge_i in NTFS-3G < 2021.8.22.(CVE-2021-39253)

In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode pathname is supplied in an NTFS image a heap buffer overflow can occur resulting in memory disclosure, denial of service and even code execution.(CVE-2021-35266)

A crafted NTFS image can cause out-of-bounds reads in ntfsattrfind and ntfsexternalattr_find in NTFS-3G < 2021.8.22.(CVE-2021-39258)

In NTFS-3G versions < 2021.8.22, when specially crafted NTFS attributes are read in the function ntfsattrpread_i, a heap buffer overflow can occur and allow for writing to arbitrary memory or denial of service of the application.(CVE-2021-33287)

A crafted NTFS image can cause an integer overflow in memmove, leading to a heap-based buffer overflow in the function ntfsattrrecord_resize, in NTFS-3G < 2021.8.22.(CVE-2021-39254)
