Internet security firm @Stake issued three security advisories for Mac OS X on Tuesday. The vulnerabilities detailed in the advisories affect Mac OS X 10.2.8 and earlier versions, but not Mac OS X 10.3 Panther. “The first details systemic flaws in the way OS X handles file and directory permissions; the second notes a kernel-level vulnerability that does not affect default installations of the operating system; and the third involves a buffer-overflow condition that may be remotely exploitable,” reports CNET Apple has not yet released patches for the security issues.
