Security Bulletin: Multiple Mozilla Firefox vulnerability issues in IBM SONAS

Summary

There are security vulnerabilities in versions of Mozilla Firefox that are shipped with versions 1.5.1.0 to 1.5.2.4 of IBM SONAS

Vulnerability Details

IBM SONAS is shipped with Mozilla Firefox. There are vulnerabilities in certain versions of Mozilla Firefox shipped in certain versions of IBM SONAS. These vulnerabilities concern the potential ability of a remote attacker to execute arbitrary code on a vulnerable system or cause a denial of service.

CVEID: CVE-2016-5284**
DESCRIPTION:** Mozilla Firefox could provide weaker than expected security, caused by the ineffectiveness of certificate pinning for add-on updates. By persuading a victim to visit a specially-crafted Web site, a remote attacker with an incorrectly issued certificate for a Mozilla Web site could exploit this vulnerability to send arbitrary add-on updates to the target user.

CVEID: CVE-2016-5257**
DESCRIPTION:** Mozilla Firefox could allow a remote attacker to execute arbitrary code on the system, caused by memory safety bugs within the browser engine. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability using unknown attack vectors to execute arbitrary code on the vulnerable system or cause a denial of service.
