Mozilla Firefox ESR < 52.7

critical Nessus Plugin ID 275690

Synopsis

A web browser installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 52.7. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2018-07 advisory.

- Mozilla developers Jet Villegas and Randell Jesup reported memory safety bugs present in Firefox ESR 52.6.
These bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. (CVE-2018-5145)

- A buffer overflow can occur when manipulating the SVG <code>animatedPathSegList</code> through script.
This results in a potentially exploitable crash. (CVE-2018-5127)

- A lack of parameter validation on IPC messages results in a potential out-of-bounds write through malformed IPC messages. This can potentially allow for sandbox escape through memory corruption in the parent process. (CVE-2018-5129)

- When packets with a mismatched RTP payload type are sent in WebRTC connections, in some circumstances a potentially exploitable crash is triggered. (CVE-2018-5130)

- Under certain circumstances the <code>fetch()</code> API can return transient local copies of resources that were sent with a <code>no-store</code> or <code>no-cache</code> cache header instead of downloading a copy from the network as it should. This can result in previously stored, locally cached data of a website being accessible to users if they share a common profile while browsing. (CVE-2018-5131)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Mozilla Firefox ESR version 52.7 or later.
