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 38.3. 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 to corrupt memory and
execute arbitrary code. (CVE-2015-4500)

- Multiple unspecified memory corruption issues exist due
to improper validation of user-supplied input. A remote
attacker can exploit these issues to corrupt memory and
execute arbitrary code. (CVE-2015-4501)

- A buffer overflow condition exists in the libvpx
component when parsing vp9 format video. A remote
attacker can exploit this, via a specially crafted vp9
format video, to execute arbitrary code. (CVE-2015-4506)

- A user-after-free error exists when manipulating HTML
media elements on a page during script manipulation of
the URI table of these elements. An attacker can exploit
this to cause a denial of service condition.
(CVE-2015-4509)

- A memory corruption issue exists in NetworkUtils.cpp. An
attacker can potentially exploit this issue to cause a
denial of service condition or to execute arbitrary
code. (CVE-2015-4517)

- An information disclosure vulnerability exists due to a
flaw that occurs when a previously loaded image on a
page is dropped into content after a redirect, resulting
in the redirected URL being available to scripts.
(CVE-2015-4519)

- Multiple security bypass vulnerabilities exist due to
errors in the handling of CORS preflight request
headers. (CVE-2015-4520)

- A memory corruption issue exists in the
ConvertDialogOptions() function. An attacker can
potentially exploit this issue to cause a denial of
service condition or to execute arbitrary code.
(CVE-2015-4521)

- An overflow condition exists in the GetMaxLength()
function. An attacker can potentially exploit this to
cause a denial of service condition or to execute
arbitrary code. (CVE-2015-4522)

- An overflow condition exists in the GrowBy() function.
An attacker can potentially exploit this to cause a
denial of service condition or to execute arbitrary
code. (CVE-2015-7174)

- An overflow condition exists in the AddText() function.
An attacker can potentially exploit this to cause a
denial of service condition or to execute arbitrary
code. (CVE-2015-7175)

- A stack overflow condition exists in the
AnimationThread() function due to a bad sscanf
argument. An attacker can potentially exploit this to
cause a denial of service condition or to execute
arbitrary code. (CVE-2015-7176)

- A memory corruption issue exists in the InitTextures()
function. An attacker can potentially exploit this issue
to cause a denial of service condition or to execute
arbitrary code. (CVE-2015-7177)

- A memory corruption issue exists in
ReadbackResultWriterD3D11::Run due to mishandling of the
return status. An attacker can potentially exploit this
issue to cause a denial of service condition or to
execute arbitrary code. (CVE-2015-7180)
