Apple updates Mac OS X for 40 flaws
The fixes -- rated "moderately critical" by vulnerability tracking firm Secunia -- addressed problems in open-source software such as ClamAV, MySQL Server and Apache Tomcat. Many open-source implementations are configured to run on the Mac OS X platform.
Roughly half of the vulnerabilities patched could be exploited to execute arbitrary code, according to the Apple update.
These bugs reside in ClamAv, ColorSync, CUPS, libxslt, MySQL Server, PHP, PSNormalizer and QuickLook.
