Mozilla has announced the availability of Firefox 43, a release that brings fixes for 21 security flaws and several feature improvements, including a 64-bit version for Windows.

Firefox 43 resolves a total of four vulnerabilities rated critical. One of them, reported by Tsubasa Iinuma, can be exploited for cross-site reading attacks (CVE-2015-7214) by bypassing cross-origin restrictions using data: and view-source: URIs to confuse protections.

A use-after-free vulnerability in WebRTC (CVE-2015-7210) that can lead to a potentially exploitable crash has been reported by Looben Yang.

Mozilla developer Kris Maglione discovered a privilege escalation issue related to WebExtension APIs (CVE-2015-7223). The vulnerability can be exploited to execute arbitrary code with the privileges of the affected WebExtension, which could lead to cross-site scripting (XSS) attacks and personal information theft.

Memory safety bugs (CVE-2015-7201 and CVE-2015-7202) found by Mozilla developers and community members have also been rated critical.

The list of high severity issues patched in Firefox 43 includes an integer underflow in the libstagefright library (Stagefright flaw reported by Zimperium’s Joshua Drake), an integer overflow when processing MP4 video files, an underflow in RTPReceiverVideo, an integer overflow when allocating extremely large textures during graphics operations, and a flaw that can lead to a crash during JavaScript variable assignments.

Researcher Masato Kinugawa reported finding a cross-origin information leak (CVE-2015-7215) that affects other browsers as well. Another vulnerability that is not limited to Mozilla products is a same-origin policy violation that can be exploited for data theft (CVE-2015-7207).

Google released an update for Chrome 47 on Tuesday to address a couple of vulnerabilities identified by the company’s own security team. This is the second security update for Chrome 47, the first being released on December 8 to patch seven issues.
