The Flash update fixes three critical vulnerabilities while the ColdFusion and Shockwave updates fix one each. Internet Explorer 10 and Chrome users will have the Flash updates installed automatically by the browser.
The three Flash vulnerabilities are CVE-2013-3344, CVE-2013-3345 and CVE-2013-3347. The first is a heap buffer overflow vulnerability that could lead to code execution and was discovered by the Google security team. The second is a memory corruption vulnerability that could lead to code execution, and was also discovered by the Google security team. The third is an integer overflow when resampling a user-supplied PCM buffer, and was discovered by Vulnazoid and reported via HP’s Zero Day Initiative.
The latest versions of Flash are available from the Adobe download center, but, warns Brian Krebs, “beware potentially unwanted add-ons, like McAfee Security Scan). To avoid this, uncheck the pre-checked box before downloading, or grab your OS-specific Flash download from here.”
