Security & Privacy

The Mozilla Foundation has released Firefox 22 for Mac OS X, which includes fixes for 14 vulnerabilities (4 Critical, 6 High, 3 Moderate, 1 Low). Mozilla fixed several issues related to memory corruption, and some of the bugs resolved in Firefox 22 are potentially exploitable, allowing for remote code execution. As typical for all software updates that resolve security issues, we strongly recommend all Firefox users apply these updates as soon as possible.

Following is a list of the security issues resolved in the Firefox 22 update:

• MFSA 2013-62 Inaccessible updater can lead to local privilege escalation
• MFSA 2013-61 Homograph domain spoofing in .com, .net and .name
• MFSA 2013-60 getUserMedia permission dialog incorrectly displays location

• MFSA 2013-56 PreserveWrapper has inconsistent behavior
• MFSA 2013-55 SVG filters can lead to information disclosure
• MFSA 2013-54 Data in the body of XHR HEAD requests leads to CSRF attacks
• MFSA 2013-53 Execution of unmapped memory through onreadystatechange event
• MFSA 2013-52 Arbitrary code execution within Profiler
