"According to the version of the libguestfs-winsupport package
installed, the EulerOS installation on the remote host is affected by
the following vulnerability :
- 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.(CVE-2019-9755)
