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-2016-2828**
DESCRIPTION:** Mozilla Firefox could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free when processing WebGL content. 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.
CVSS Base Score: 8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113865 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H)

CVEID: CVE-2016-2831**
DESCRIPTION:** Mozilla Firefox could allow a remote attacker to bypass security restrictions, caused by an error when fullscreen and pointerlock requests are done in combination with closing windows. By persuading a victim to visit a specially crafted Web site, an attacker could exploit this vulnerability to create a pointerlock within a fullscreen window without user permission.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113867 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N)

CVEID: CVE-2016-2818**
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.
CVSS Base Score: 8.8

CVEID: CVE-2016-2819**
DESCRIPTION:** Mozilla Firefox is vulnerable to a buffer overflow, caused by improper bounds checking when parsing HTML5 fragments. By inserting an HTML fragment into an existing document, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 8.8

CVEID: CVE-2016-2821**
DESCRIPTION:** Mozilla Firefox could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free in contenteditable mode. 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.
CVSS Base Score: 8.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113860 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID: CVE-2016-2822**
DESCRIPTION:** Mozilla Firefox could allow a remote attacker to conduct spoofing attacks, caused by an error when using the SELECT element. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to spoof the contents of the addressbar to redirect a user to a malicious Web site that would appear to be trusted.
CVSS Base Score: 4.3
