Details

Matthew Noorenberghe discovered that whitelisted Mozilla domains could

make UITour API calls from background tabs. If one of these domains were

compromised and open in a background tab, an attacker could potentially

exploit this to conduct clickjacking attacks. (CVE-2015-0819)

Jan de Mooij discovered an issue that affects content using the Caja

Compiler. If web content loads specially crafted code, this could be used

to bypass sandboxing security measures provided by Caja. (CVE-2015-0820)

Armin Razmdjou discovered that opening hyperlinks with specific mouse

and key combinations could allow a Chrome privileged URL to be opened

without context restrictions being preserved. If a user were tricked in to

opening a specially crafted website, an attacker could potentially exploit

this to bypass security restrictions. (CVE-2015-0821)

Armin Razmdjou discovered that contents of locally readable files could

be made available via manipulation of form autocomplete in some

circumstances. If a user were tricked in to opening a specially crafted

website, an attacker could potentially exploit this to obtain sensitive

information. (CVE-2015-0822)

Atte Kettunen discovered a use-after-free in the OpenType Sanitiser (OTS)

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. (CVE-2015-0823)

Atte Kettunen discovered a crash when drawing images using Cairo 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. (CVE-2015-0824)

Atte Kettunen discovered a buffer underflow during playback of MP3 files

in some circumstances. If a user were tricked in to opening a specially

crafted website, an attacker could potentially exploit this to obtain

sensitive information. (CVE-2015-0825)

Atte Kettunen discovered a buffer overflow during CSS restyling 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-2015-0826)

Abhishek Arya discovered an out-of-bounds read and write when rendering

SVG content in some circumstances. If a user were tricked in to opening

a specially crafted website, an attacker could potentially exploit this

to obtain sensitive information. (CVE-2015-0827)

A buffer overflow was discovered in libstagefright during video playback

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-2015-0829)

Daniele Di Proietto discovered that WebGL could cause a crash 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. (CVE-2015-0830)

Paul Bandha discovered a use-after-free in IndexedDB. 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-2015-0831)

Muneaki Nishimura discovered that a period appended to a hostname could

bypass key pinning and HSTS in some circumstances. A remote attacker could

potentially exloit this to conduct a Man-in-the-middle (MITM) attack.

(CVE-2015-0832)

Alexander Kolesnik discovered that Firefox would attempt plaintext

connections to servers when handling turns: and stuns: URIs. A remote

attacker could potentially exploit this by conducting a Man-in-the-middle

(MITM) attack in order to obtain credentials. (CVE-2015-0834)



Carsten Book, Christoph Diehl, Gary Kwong, Jan de Mooij, Liz Henry, Byron

Campen, Tom Schuster, Ryan VanderMeulen, Christian Holler, Jesse Ruderman,

Randell Jesup, Robin Whittleton, Jon Coppeard, and Nikhil Marathe

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-2015-0835, CVE-2015-0836)
