According to the version of the cifs-utils package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  • Stack-based buffer overflow in cifskey.c or cifscreds.c in cifs-utils before 6.4, as used in pam_cifscreds, allows remote attackers to have unspecified impact via unknown vectors.(CVE-2014-2830)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
