Mark your calendars, IT security enthusiasts. April 13, 2010, Tuesday, is the day when Microsoft is releasing patches for Microsoft Windows and Microsoft Office. It is a big day, and it actually has been dubbed as Microsoft’s Patch Tuesday. More than Microsoft, however, Adobe is also planning to release patches of its own. The patches are for Adobe Acrobat and Adobe Reader. All in all, there will be 27 issues to be addressed by the patches.

Do we have any details about the patches? People can wait for a couple more days, of course, but for those of you who are hungry for information – as I am sure you are – you’re lucky enough to have someone like Amol Sarwate. He’s the manager of the Vulnerability Research Lab of Qualys. He says:

“There are 11 security bulletins that affect a range of Windows operating system components as well as Microsoft Office and Microsoft Exchange. This is a fairly large update and will keep system administrators busy on Patch Tuesday. Out of the 11 security bulletins, five are rated Critical and affect components in Windows 2000, XP, Vista, 2003, 2008 and Windows 7. If left un-patched, an attacker could execute code or programs on the victim’s machine and therefore all are categorized as remote code execution.”

Both companies are releasing the patches through their automatic update features. If you’re the safe kind, your auto updates are probably enabled. If you have experienced extreme slowdown because of these updates before and you’ve disabled them, then better turn them on before Patch Tuesday. You wouldn’t want to miss this.
