What is CVE-2019-9755?
CVE-2019-9755 is a high-severity vulnerability in Redhat Enterprise Linux, published on 5 Jun 2019. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
