ITS Advisory Number: 
2014-053
Date(s) Issued: 
Tuesday, June 10, 2014
Subject: 
Multiple Vulnerabilities in Mozilla Products Could Allow Remote Code Execution
Overview: 

Multiple vulnerabilities have been discovered in Mozilla Firefox and Thunderbird applications and Netscape Portable Runtime which could allow remote code execution. Mozilla Firefox is a web browser used to access the Internet. Mozilla Thunderbird is an email client. Netscape Portable Runtime makes all operating systems it supports appear the same to Mozilla-style web browsers.

Successful exploitation of these vulnerabilities could result in either an attacker gaining the same privileges as the logged on user, or gaining session authentication credentials. Depending on the privileges associated with the user, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights.

Systems Affected: 
  • Firefox versions prior to 30
  • Firefox ESR versions prior to 24.6
  • Thunderbird versions prior to 24.6
  • Netscape Portable Runtime prior to 4.10.6

Description: 

Eight vulnerabilities have been reported for various Mozilla products. Details of the vulnerabilities are as follows:

Successful exploitation could result in an attacker gaining the same privileges as the affected application. Depending on the privileges associated with the application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Failed exploit attempts will likely cause denial-of-service conditions.

Actions: 
  • Update vulnerable Mozilla products immediately after appropriate testing.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Remind users not to open email attachments from unknown users or suspicious emails from trusted sources.
