Ubuntu Security Notice 2743-4 - USN-2743-1 fixed vulnerabilities in Firefox. After upgrading, some users reported problems with bookmark creation and crashes in some circumstances. This update fixes the problem. Andrew Osmond, Olli Pettay, Andrew Sutherland, Christian Holler, David Major, Andrew McCreight, Cameron McCormack, Bob Clary and Randell Jesup 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. Various other issues were also addressed.
