Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Security restrictions bypass (CVE-ID: CVE-2018-2783)

The vulnerability allows a remote unauthenticated attacker to obtain potentially sensitive information and write arbitrary files on the target system.

The weakness exists in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE due to improper security restrictions. A remote attacker can create, delete or modify critical data or all Java SE, Java SE Embedded, JRockit accessible data and gain unauthorized access to critical data or complete access to all Java SE, Java SE Embedded, JRockit accessible data.

2) 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


3) 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.

4) Security restrictions bypass (CVE-ID: CVE-2018-3180)

The vulnerability allows a remote attacker to bypass security restrictions on the target system.

The weakness exists due to insufficient privileges and access controls. A remote attacker can bypass security restrictions to conduct further attacks.

5) Buffer overflow (CVE-ID: CVE-2018-12547)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to the jio_snprintf() and jio_vsnprintf() native methods ignored the length parameter. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
