CVE-2018-3263 : Security Advisory and Response

A vulnerability has been discovered in the Sudo subcomponent of the Solaris component of Oracle Sun Systems Products Suite (specifically affecting version 11.3). This vulnerability, while difficult to exploit, can be used by an attacker with network access through various protocols to compromise Solaris. If successfully exploited, unauthorized actions such as updating, inserting, or deleting certain data accessible by Solaris, as well as reading a subset of Solaris data without authorization, may occur. In addition, the vulnerability can lead to a partial denial of service (partial DOS) in Solaris. The CVSS 3.0 Base Score for this vulnerability is 5.6, with impacts on confidentiality, integrity, and availability. The CVSS Vector is as follows: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L).
