Christian Holler, Terrence Cole, Jesse Ruderman, Gary Kwong, Eric

Rescorla, Jonathan Kew, Dan Gohman, Ryan VanderMeulen, Carsten Book,

Andrew Sutherland, Byron Campen, Nicholas Nethercote, Paul Adenot, David

Baron, Julian Seward and Sotaro Ikeda 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-2014-1477,

CVE-2014-1478)

Cody Crews discovered a method to bypass System Only Wrappers. An attacker

could potentially exploit this to steal confidential data or execute code

with the privileges of the user invoking Firefox. (CVE-2014-1479)

Jordi Chancel discovered that the downloads dialog did not implement a

security timeout before button presses are processed. An attacker could

potentially exploit this to conduct clickjacking attacks. (CVE-2014-1480)

Fredrik Lönnqvist discovered a use-after-free in Firefox. An attacker

could potentially exploit this to cause a denial of service via

application crash, or execute arbitrary code with the priviliges of the

user invoking Firefox. (CVE-2014-1482)

Jordan Milne discovered a timing flaw when using document.elementFromPoint

and document.caretPositionFromPoint on cross-origin iframes. An attacker

could potentially exploit this to steal confidential imformation.

(CVE-2014-1483)

Frederik Braun discovered that the CSP implementation in Firefox did not

handle XSLT stylesheets in accordance with the specification, potentially

resulting in unexpected script execution in some circumstances

(CVE-2014-1485)

Arthur Gerkis discovered a use-after-free in Firefox. An attacker could

potentially exploit this to cause a denial of service via application

crash, or execute arbitrary code with the priviliges of the user invoking

Firefox. (CVE-2014-1486)

Masato Kinugawa discovered a cross-origin information leak in web worker

error messages. An attacker could potentially exploit this to steal

confidential information. (CVE-2014-1487)

Yazan Tommalieh discovered that web pages could activate buttons on the

default Firefox startpage (about:home) in some circumstances. An attacker

could potentially exploit this to cause data loss by triggering a session

restore. (CVE-2014-1489)

Soeren Balko discovered a crash in Firefox when terminating web workers

running asm.js code in some circumstances. An attacker could potentially

exploit this to execute arbitrary code with the priviliges of the user

invoking Firefox. (CVE-2014-1488)

Several issues were discovered with ticket handling in NSS. An attacker

could potentially exploit these to cause a denial of service or bypass

cryptographic protection mechanisms. (CVE-2014-1490, CVE-2014-1491)

Boris Zbarsky discovered that security restrictions on window objects

could be bypassed under certain circumstances. (CVE-2014-1481)
