Apple Improves OS X Security with Mavericks Release

Most of the security components in the Mavericks release are not currently available in the most recent OS X 10.8 update, which provides a good reason for users of older OS X versions to update as soon as possible. The last OS X 10.8 Mountain Lion release prior to this week's 10.9 Mavericks update is the 10.8.5 release which debuted in September.

One of the new updates in 10.9 is a fix for a vulnerability in OS X's application firewall. The flaw is identified as CVE-2013-5165 and has an exploitability score of 10, meaning it can be remotely exploited by an attacker without authentication. Apple's security notification on the issue explains that "the --blockApp option did not properly block applications from receiving network connections."
