Firefox ESR < 38.5 Multiple Vulnerabilities (Mac OS X)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


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 38.5. It is, therefore, affected by the following
vulnerabilities :

- Multiple unspecified memory corruption issues exist due
to improper validation of user-supplied input. A remote
attacker can exploit these issues by convincing a user
to visit a specially crafted web page, resulting in the
execution of arbitrary code. (CVE-2015-7201)

- A flaw exists in the RtpHeaderParser::Parse() function
due to improper handling of RTP headers. An
unauthenticated, remote attacker can exploit this, via
specially crafted RTP headers, to execute arbitrary
code. (CVE-2015-7205)

- A use-after-free error exists due to improper prevention
of datachannel operations on closed PeerConnections. An
attacker can exploit this to dereference already freed
memory, resulting in the execution of arbitrary code.
(CVE-2015-7210)

- An overflow condition exists in the AllocateForSurface()
function due to improper validation of user-supplied
input when handling texture allocation in graphics
operations. An attacker can exploit this to execute
arbitrary code. (CVE-2015-7212)

- An integer overflow condition exists in the
readMetaData() function due to improper validation of
user-supplied input when handling a specially crafted
MP4 file. An attacker can exploit this to execute
arbitrary code. (CVE-2015-7213)

- A same-origin bypass vulnerability exists due to
improper handling of 'data:' and 'view-source:' URIs. An
attacker can exploit this to read data from cross-site
URLs and local files. (CVE-2015-7214)

- An integer underflow condition exists in the bundled
version of libstagefright in the parseChunk() function
that is triggered when handling 'covr' chunks. An
unauthenticated, remote attacker can exploit this, via
specially crafted media content, to crash the
application or execute arbitrary code. (CVE-2015-7222)
