Rewterz Threat Advisory – Oracle Java SE Embedded Multiple Vulnerabilities

October 17, 2018

Oracle Java SE Embedded 8.x was found vulnerable to multiple issues which can be exploited to cause Denial of Service, data manipulation and information disclosure.

 

 

IMPACT:  NORMAL

 

 

PUBLISH DATE:  17-10-2018

 

 

OVERVIEW

 

 

Multiple vulnerabilities have been reported in Oracle Java SE Embedded. Local users with malicious intent can exploit these vulnerabilities to reveal sensitive information or manipulate data, cause a Denial of Service or compromise a vulnerable system.

 

Updates have been released by the vendor that fix the vulnerabilities.

 

 

ANALYSIS

 

 

Following CVE numbers have been assigned to the vulnerabilities found in Oracle Java SE Embedded. However, most of these have not been defined in details.

 

CVE-2018-3211

CVE-2018-3169

CVE-2018-3214

CVE-2018-3136

CVE-2018-3139

CVE-2018-3180

CVE-2018-3183

CVE-2018-13785

CVE-2018-3149

 

CVE-2018-13785

In libpng 1.6.34, row_factor is wrongly calculated in the png_check_chunk_length function (pngrutil.c). This makes it capable of triggering an integer overflow and causing resultant divide-by-zero, while processing a crafted PNG file. This will lead to a denial of service (DoS).

 

 

The vendor has released a Critical Patch Update which contains 12 new security fixes for Oracle Java SE, 11 of which were found to be exploitable via remote sources, without being authenticated. An attacker can exploit these over a network without providing user credentials.

 

 

AFFECTED PRODUCTS

 

 

Oracle Java SE Embedded 8.x

(The vulnerabilities are reported in version 8u181)

 

 

UPDATES

 

 

Owing to periodic reports of malicious attempts by attackers, Oracle keeps releasing fresh fixes. However, some incidents have been reported in which customers didn’t apply relevant patches on time and attackers were able to successfully exploit the vulnerabilities.  Therefore, Oracle strongly recommends that customers only use actively-supported versions and apply Critical Patch Update fixes without delay.
