Cisco releases patch to fix three high security bugs

On January 17, Cisco releases the patches for Cisco Unified Customer Voice Portal (CVP), Cisco Email Security Appliance (ESA) and Cisco NX-OS Software. An attacker can exploit these vulnerabilities to cause a denial of service (DoS) condition or escalate privilege level and gain root access. CVEs of the three critical vulnerabilities are CVE-2018-0102, CVE-2018-0095, and CVE-2018-0086. Users should install patches as soon as possible.
