Description
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.
Statement
This flaw has a lower impact on Red Hat Enterprise Linux because the ntfs-3g tool is run in a supermin appliance, which is similar to a virtual machine instantiated on the fly, and it does not have the SUID bit set. Thus an attacker is very limited on what he can do to the vulnerable system.
