Firefox < 38.0 Multiple Vulnerabilities

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

- A privilege escalation vulnerability exists in the
Inter-process Communications (IPC) implementation due
to a failure to validate the identity of a listener
process. (CVE-2011-3079)

- An issue exists in the Mozilla updater in which DLL
files in the current working directory or Windows
temporary directories will be loaded, allowing the
execution of arbitrary code. (CVE-2015-0833 /
CVE-2015-2720)

- Multiple memory corruption issues exist within the
browser engine. A remote attacker can exploit these to
corrupt memory and execute arbitrary code.
(CVE-2015-2708, CVE-2015-2709)

- A buffer overflow condition exists in SVGTextFrame.cpp
when rendering SVG graphics that are combined with
certain CSS properties due to improper validation of
user-supplied input. A remote attacker can exploit this
to cause a heap-based buffer overflow, resulting in the
execution of arbitrary code. (CVE-2015-2710)

- A security bypass vulnerability exists due to the
referrer policy not being enforced in certain situations
when opening links (e.g. using the context menu or a
middle-clicks by mouse). A remote attacker can exploit
this to bypass intended policy settings. (CVE-2015-2711)

- An out-of-bounds read and write issue exists in the
CheckHeapLengthCondition() function due to improper
JavaScript validation of heap lengths. A remote attacker
can exploit this, via a specially crafted web page, to
disclose memory contents. (CVE-2015-2712)

- A use-after-free error exists due to improper processing
of text when vertical text is enabled. A remote attacker
can exploit this to dereference already freed memory.
(CVE-2015-2713)

- A use-after-free error exists in the
RegisterCurrentThread() function in nsThreadManager.cpp
due to a race condition related to media decoder threads
created during the shutdown process. A remote attacker
can exploit this to dereference already freed memory.
(CVE-2015-2715)

- A buffer overflow condition exists in the
XML_GetBuffer() function in xmlparse.c due to improper
validation of user-supplied input when handling
compressed XML content. An attacker can exploit this to
cause a buffer overflow, resulting in the execution of
arbitrary code. (CVE-2015-2716)

- An integer overflow condition exists in the parseChunk()
function in MPEG4Extractor.cpp due to improper handling
of MP4 video metadata in chunks. A remote attacker can
exploit this, via specially crafted media content, to
cause a heap-based buffer overflow, resulting in the
execution of arbitrary code. (CVE-2015-2717)

- A security bypass vulnerability exists in WebChannel.jsm
due to improper handling of message traffic. An
untrusted page hosting a trusted page within an iframe
can intercept webchannel responses for the trusted page.
This allows a remote attacker, via a specially crafted
web page, to bypass origin restrictions, resulting in
the disclosure of sensitive information. (CVE-2015-2718)

- Multiple integer overflow conditions exist in the
bundled libstagefright component due to improper
validation of user-supplied input when processing MPEG4
sample metadata. A remote attacker can exploit this, via
specially crafted media content, to execute arbitrary
code. (CVE-2015-4496)
