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-2018-17466 DESCRIPTION: Mozilla Firefox is vulnerable to a buffer overflow, caused by improper bounds checking and an out-of-bounds read in TextureStorage11 within the ANGLE graphics library. 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 the application to crash.

CVEID: CVE-2018-12405 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.

CVEID: CVE-2018-18492 DESCRIPTION: Mozilla Firefox could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free after deleting a selection element due to a weak reference to the select element in the options collection. 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-2018-18493 DESCRIPTION: Mozilla Firefox is vulnerable to a buffer overflow, caused by improper bounds checking in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions. 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 the application to crash.

CVEID: CVE-2018-18494 DESCRIPTION: Mozilla Firefox could allow a remote attacker to bypass security restrictions. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability using performance.getEntries() to bypass same-origin policy and steal cross-origin URLs.
CVSS Base Score: 6.5

CVEID: CVE-2018-18498 DESCRIPTION: Mozilla Firefox could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow during buffer size calculations for images when a raw value is used instead of the checked value. 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.

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
