Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2017-18249 A race condition was discovered in the disk space allocator of F2FS. A user with access to an F2FS volume could use this to cause a denial of service or other security impact. CVE-2018-1128, CVE-2018-1129 The cephx authentication protocol used by Ceph was susceptible to replay attacks, and calculated signatures incorrectly. These vulnerabilities in the server required changes to authentication that are incompatible with existing clients.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
