Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2018-1517)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via specially crafted String data


2) Path traversal (CVE-ID: CVE-2018-1656)

The vulnerability allows a remote attacker to conduct directory traversal attack on the target system.

The weakness exists due to insufficient protection of path traversal attacks when extracting compressed dump files. A remote attacker can conduct directory traversal attack and extract compressed dump files.

3) Input validation error (CVE-ID: CVE-2018-2940)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Libraries). Supported versions that are affected are Java SE: 6u191, 7u181, 8u172 and 10.0.1; Java SE Embedded: 8u171. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.0 Base Score 4.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N).


4) Denial of service (CVE-ID: CVE-2018-2952)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to unknown flaw. A remote attacker can cause a partial denial of service under unspecified conditions.

5) Input validation error (CVE-ID: CVE-2018-2973)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: JSSE). Supported versions that are affected are Java SE: 6u191, 7u181, 8u172 and 10.0.1; Java SE Embedded: 8u171. Difficult to exploit vulnerability allows unauthenticated attacker with network access via SSL/TLS to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.0 Base Score 5.9 (Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N).


6) Privilege escalation (CVE-ID: CVE-2018-12539)

The vulnerability allows a local unauthenticated attacker to gain elevated privileges on the target system.

The weakness exists due to the failure to restrict the use of Java Attach API to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and use Attach API operations to only the process owner. A local attacker can conduct directory traversal attack and extract compressed dump files.
