Mozilla Firefox was updated to 38.2.1 ESR, fixing two severe security bugs. (bsc#943608)

• MFSA 2015-94/CVE-2015-4497 (bsc#943557): Use-after-free when resizing canvas element during restyling
• MFSA 2015-95/CVE-2015-4498 (bsc#943558): Add-on notification bypass through data URLs

Use-after-free vulnerability in the CanvasRenderingContext2D implementation in Mozilla Firefox before 40.0.3 and Firefox ESR 38.x before 38.2.1 allows remote attackers to execute arbitrary code by leveraging improper interaction between resize events and changes to Cascading Style Sheets (CSS) token sequences for a CANVAS element.

A use-after-free was discovered when resizing a canvas element during 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-2015-4497)

Bas Venis discovered that the addon install permission prompt could be bypassed using data: URLs in some circumstances. It was also discovered that the installation notification could be made to appear over another site. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to install a malicious addon. (CVE-2015-4498)
