Microsoft, Apple and Adobe provide new updates to their users. While Microsoft plugs 14 holes alone in its PowerPoint software, Apple fixes 67 security holes in its Mac OS X operating system and in the Safari web browser. Adobe closes the security holes in its PDF reader software.
The PowerPoint updates from Security Bulletin MS09-017 close the security hole which already got actively exploited on the net and other, currently unknown vulnerabilities. The patches for PowerPoint for Macs are still missing though. Microsoft urges its users to install the update as soon as possible as the company expects exploits for the other holes to surface soon.
Apple released Mac OS X 10.5.7 and Safari 3.2.3. Apple and Safari users should install those updates immediately, too. The updates for Adobe Reader and Acrobat should be installed ASAP as well.
