Massive Apple Patches in the Shadow of Microsoft Patch Tuesday

- May 13th, 2009

 

Given all the attention around Microsoft’s patch release for Office PowerPoint in yesterday’s Patch Tuesday, Apple’s release of 67+ patches and the huge 286 MB Apple patch seems to have slipped under the radar. This is another reminder for IT administrators that software vulnerabilities are not a Microsoft “exclusive” issue and you are just as likely to suffer an intrusion initiated from a vulnerability in a non-Microsoft application or software add-on even if your Microsoft products are fully patched and up to date. In today’s heterogeneous enterprise environments it is just as important to patch “wide” across multiple vendors products as it is to “patch fast” to beat the bad guys to the punch. For a complete rundown of this month’s patches and vulnerabilities, take a listen to my podcast or read my blog. Just in case you missed it, here are the details of yesterday’s colossal Apple patch bulletins: APPLE-SA-2009-05-12 Security Update 2009-002 / Mac OS X v10.5.7 Security Update 2009-002 / Mac OS X v10.5.7 is now available and addresses the following:

This update addresses the issue by performing additional validation of the output data. This issue does not affect systems prior to Mac OS X v10.5.
