The new kernel update published earlier this week addresses a total of 39 security vulnerabilities for the long-term supported Ubuntu 16.04 LTS (Xenial Xerus) operating system series and its official derivatives, including Kubuntu, Lubuntu, Xubuntu, Ubuntu MATE, Ubuntu Kylin, and Ubuntu Studio. The most severe vulnerabilities fixed in this new kernel update affected Linux kernel's USB over IP implementation, allowing remote attackers to either crash the vulnerable system or cause excessive memory consumption through denial of service (DoS attacks). More information about the fixed issues can be found in the security advisory.
