High Nessus Network Monitor Plugin ID 9378

Synopsis

The remote host has a web browser installed that is vulnerable to multiple attack vectors.

Description

Versions of Mozilla Firefox ESR earlier than 38.8 are unpatched for the following 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 38.8 or later.
