An integer underflow issue exists in ntfs-3g 2017.3.23. A local attacker could potentially exploit this by running /bin/ntfs-3g with specially crafted arguments from a specially crafted directory to cause a heap buffer overflow, resulting in a crash or the ability to execute arbitrary code. In installations where /bin/ntfs-3g is a setuid-root binary, this could lead to a local escalation of privileges.

Affected: Ubuntu:16.04:LTS: ntfs-3g, Ubuntu:18.04:LTS: ntfs-3g

A heap buffer overflow was discovered in NTFS-3G when executing it with a relative mount point path that is too long. A local attacker could potentially exploit this to execute arbitrary code as the administrator.
