Supported versions that are affected are Java SE: 7u171, 8u162 and 10; Java SE Embedded: 8u161; JRockit: R28.3.17. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded, JRockit. Note: Applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service. CVSS 3.0 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). ### From the Ubuntu Security Team It was discovered that the JAXP component of OpenJDK in some situations did not properly limit the amount of memory allocated when performing deserialization. An attacker could use this to cause a denial of service (memory exhaustion). ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | openjdk-7 | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Fixed 7u181-2.6.14-0ubuntu0.1 | | openjdk-8 | 18.04 LTS bionic | Fixed 8u171-b11-0ubuntu0.18.04.1 | | 17.10 artful | Fixed 8u171-b11-0ubuntu0.17.10.1 | | 16.04 LTS xenial | Fixed 8u171-b11-0ubuntu0.16.04.1 | | 14.04 LTS trusty | Not in release | --- * [How can I get the fixes?](https://ubuntu.com/security/cves/about#security) * [What do statuses mean?](https://ubuntu.com/security/cves/about#statuses) ## Severity score breakdown CVSS version: CVSS v3.0 **Base score** 5.3 · Medium * Base metrics | Parameter | Value | | --- | --- | | Attack vector | Network | | Attack complexity | Low | | Privileges required | None | | User interaction | None | | Scope | Unchanged | | Confidentiality impact | None | | Integrity impact | None | | Availability impact | Low | * Scores | Parameter | Value | | --- | --- | | Base score | 5.3 · Medium | | Exploitability score | - | | Impact score | - | **Vector:** CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L ## References * [MITRE](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-2799) * [NVD](https://nvd.nist.gov/vuln/detail/CVE-2018-2799) * [Launchpad](https://launchpad.net/bugs/cve/CVE-2018-2799) * [Debian](https://security-tracker.debian.org/tracker/CVE-2018-2799) ### Related Ubuntu Security Notices (USN) + [USN-3691-1](https://usn.ubuntu.com/USN-3691-1) + OpenJDK 7 vulnerabilities + 21 June 2018 + [USN-3644-1](https://usn.ubuntu.com/USN-3644-1) + OpenJDK 8 vulnerabilities + 11 May 2018 ### Other references * *
