Firefox < 46 Multiple Vulnerabilities

High Nessus Plugin ID 90793

Synopsis

The remote Windows host contains a web browser that is affected by multiple vulnerabilities.

Description

The version of Firefox installed on the remote Windows host is prior to 46. It is, therefore, affected by multiple vulnerabilities :

- Multiple memory corruption issues exist that allow an attacker to corrupt memory, resulting in the execution of arbitrary code. (CVE-2016-2804, CVE-2016-2806, CVE-2016-2807)

- A flaw exists due to improper validation of user-supplied input when handling the 32-bit generation count of the underlying HashMap. A context-dependent attacker can exploit this to cause a buffer overflow condition, resulting in a denial of service or the execution of arbitrary code. (CVE-2016-2808)

- A local privilege escalation vulnerability exists in the Maintenance Service updater due to improper handling of long log file paths. A local attacker can exploit this to delete arbitrary files and gain elevated privileges.
(CVE-2016-2809)

- A remote code execution vulnerability exists due to a use-after-free error in the BeginReading() function. A context-dependent attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-2811)

- A remote code execution vulnerability exists due to a race condition in ServiceWorkerManager in the get() function. A context-dependent attacker can exploit this to execute arbitrary code. (CVE-2016-2812)

- A heap buffer overflow condition exists in the Google Stagefright component due to improper validation of user-supplied input when handling CENC offsets and the sizes table. A context-dependent attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-2814)

- A security bypass vulnerability exists due to the Content Security Policy (CSP) not being properly applied to web content sent with the 'multipart/x-mixed-replace' MIME-type. A context-dependent attacker can exploit this to bypass CSP protection. (CVE-2016-2816)

- A cross-site scripting (XSS) vulnerability exists due to improper restriction of unprivileged 'javascript: URL' navigation. A context-dependent attacker can exploit this, via a specially crafted request, to execute arbitrary script code in the context of a user's browser session. (CVE-2016-2817)

- A flaw exists in the Firefox Health Report that is triggered when it accepts any content document events that are presented in its iframe. A context-dependent attacker can exploit this to manipulate sharing preferences. (CVE-2016-2820)

Solution

Upgrade to Firefox version 46 or later.
