Ubuntu Security Notice USN-2833-1
December 15, 2015

firefox vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.10
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Firefox could be made to crash or run programs as your login if it
opened a malicious website.

Software Description:
- firefox: Mozilla Open Source web browser

Details:

Andrei Vaida, Jesse Ruderman, Bob Clary, Christian Holler, Jesse Ruderman,
Eric Rahm, Robert Kaiser, Harald Kirschner, and Michael Henretty
discovered multiple memory safety issues in Firefox. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user invoking
Firefox. (CVE-2015-7201, CVE-2015-7202)

Ronald Crane discovered three buffer overflows through code inspection.
If a user were tricked in to opening a specially crafted website, an
attacker could potentially exploit these to cause a denial of service via
application crash, or execute arbitrary code with the privileges of the
user invoking Firefox. (CVE-2015-7203, CVE-2015-7220, CVE-2015-7221)

Cajus Pollmeier discovered a crash during javascript variable assignments
in some circumstances. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to execute
arbitrary code with the privileges of the user invoking Firefox.
(CVE-2015-7204)

Ronald Crane discovered a buffer overflow through code inspection. If a
user were tricked in to opening a specially crafted website, an attacker
could potentially exploit this to cause a denial of service via
application crash, or execute arbitrary code with the privileges of the
user invoking Firefox. (CVE-2015-7205)

It was discovered that it is possible to read cross-origin URLs following
a redirect if performance.getEntries() is used with an iframe to host a
page. If a user were tricked in to opening a specially crafted website, an
attacker could potentially exploit this to bypass same-origin
restrictions. (CVE-2015-7207)

It was discovered that Firefox allows for control characters to be set in
cookies. An attacker could potentially exploit this to conduct cookie
injection attacks on some web servers. (CVE-2015-7208)

Looben Yang discovered a use-after-free in WebRTC when closing channels in
some circumstances. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to cause a
denial of service via application crash, or execute arbitrary code with
the privileges of the user invoking Firefox. (CVE-2015-7210)

Abdulrahman Alqabandi discovered that hash symbol is incorrectly handled
when parsing data: URLs. An attacker could potentially exploit this to
conduct URL spoofing attacks. (CVE-2015-7211)

Abhishek Arya discovered an integer overflow when allocating large
textures. If a user were tricked in to opening a specially crafted
website, an attacker could potentially exploit this to cause a denial of
service via application crash, or execute arbitrary code with the
privileges of the user invoking Firefox. (CVE-2015-7212)

Ronald Crane dicovered an integer overflow when processing MP4 format
video in some circumstances. If a user were tricked in to opening a
specially crafted website, an attacker could potentially exploit this to
cause a denial of service via application crash, or execute arbitrary code
with the privileges of the user invoking Firefox. (CVE-2015-7213)

Tsubasa Iinuma discovered a way to bypass same-origin restrictions using
data: and view-source: URLs. If a user were tricked in to opening a
specially crafted website, an attacker could potentially exploit this to
obtain sensitive information and read local files. (CVE-2015-7214)

Masato Kinugawa discovered a cross-origin information leak in error events
in web workers. An attacker could potentially exploit this to obtain
sensitive information. (CVE-2015-7215)

Gustavo Grieco discovered that the file chooser crashed on malformed
images due to flaws in the Jasper library. If a user were tricked in to
opening a specially crafted website, an attacker could potentially
exploit this to cause a denial of service.
(CVE-2015-7216, CVE-2015-7217)

Stuart Larsen discoverd two integer underflows when handling malformed
HTTP/2 frames in some circumstances. If a user were tricked in to opening
a specially crafted website, an attacker could potentially exploit these
to cause a denial of service via application crash. (CVE-2015-7218,
CVE-2015-7219)

Gerald Squelart discovered an integer underflow in the libstagefright
library when parsing MP4 format video in some circumstances. If a user
were tricked in to opening a specially crafted website, an attacker could
potentially exploit this to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user invoking
Firefox. (CVE-2015-7222)

Kris Maglione discovered a mechanism where web content could use
WebExtension APIs to execute code with the privileges of a particular
WebExtension. If a user were tricked in to opening a specially crafted
website with a vulnerable extension installed, an attacker could
potentially exploit this to obtain sensitive information or conduct
cross-site scripting (XSS) attacks. (CVE-2015-7223)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 15.10:
firefox 43.0+build1-0ubuntu0.15.10.1

Ubuntu 15.04:
firefox 43.0+build1-0ubuntu0.15.04.1
