Security Bulletin: Multiple Mozilla Firefox vulnerabilities in IBM SONAS

Summary

There are security vulnerabilities in versions of Mozilla Firefox that are shipped with versions 1.5.1.0 to 1.5.2.10 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-2019-9791 DESCRIPTION: Mozilla Firefox is vulnerable to a denial of service, caused by a type confusion between arbitrary objects when compiled through the IonMonkey just-in-time (JIT) compiler and when the constructor function is entered through on-stack replacement (OSR). By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to cause a denial of service.

CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)

CVEID: CVE-2019-9792 DESCRIPTION: Mozilla Firefox is vulnerable to a denial of service, caused by the leaking of JS_OPTIMIZED_OUT magic value to script by IonMonkey. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 6.5

CVEID: CVE-2019-9790 DESCRIPTION: Mozilla Firefox could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free when removing in-use DOM elements. 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.

CVEID: CVE-2019-9796 DESCRIPTION: Mozilla Firefox could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free when the SMIL animation controller incorrectly registers with the refresh driver twice. 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.

CVEID: CVE-2019-9793 DESCRIPTION: Mozilla Firefox is vulnerable to a buffer overflow, caused by improper bounds checking when Spectre mitigations are disabled. By persuading a victim to visit a specially-crafted Web site, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause a denial of service.

Affected Products and Versions

IBM SONAS
The product is affected when running code releases 1.5.1.0 to 1.5.2.10

Remediation/Fixes

A fix for these issues is in version 1.5.2.11 of IBM SONAS. Customers running an affected version of IBM SONAS should upgrade to 1.5.2.11 or a later version, so that the fix gets applied.

Workarounds and Mitigations

Workaround(s) :
Normal operation of IBM SONAS does not require or call for customers to use Firefox to access the Internet. Although IBM recommends that you install a level of IBM SONAS code with a fix, you can avoid these vulnerabilities by not using Mozilla Firefox within your IBM SONAS system to access the Internet.

Mitigation: None
