Firefox ESR < 38.8 Multiple Vulnerabilities (Mac OS X)

High Nessus Plugin ID 90788

Synopsis

The remote Mac OS X host contains a web browser that is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote Mac OS X host is prior to 38.8. 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-2016-2805, 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 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)

Solution

Upgrade to Firefox ESR version 38.8 or later.
