I’ve never liked Adobe’s “free” pdf reader, as it has hung my computer more times than any other single software glitch. Many times I’ve been frozen up and had to do a hard reboot simply because I’ve tried to open pdf files which failed.
I’ve been scolded repeatedly for not “upgrading” to the “latest version” as I should (“latest” versions are an unending computer hassle, of course), but in light of the latest news, I’m beginning to think I should just try to do without pdf files entirely:

A dangerous and unpatched vulnerability in Adobe’s PDF-reading software has been around a lot longer than previously realized.
The bug, first reported late last week, has caused concern because it is easy to exploit and it is not expected to be patched by Adobe for several weeks. Symantec told Adobe about the flaw, which lies in the Acrobat and Reader software, on Feb. 12, but on Monday security vendor Sourcefire said that an analysis of its database of malicious software shows that attackers have actually been using the attack for more than six weeks.
Sourcefire has found samples dating back to Jan. 9, said Matt Watchinski, Sourcefire’s senior director of vulnerability research.
To date, the bug has been used in small-scale attacks against specially targeted individuals. Symantec says it has tracked only 100 attacks, but attacks have been increasing as attack code that exploits the flaw has been made public. The bug affects both Mac and Windows users.

Well, at least this time my Mac friends won’t be able to smugly say “I TOLD YOU SO!” and brag about how they “no longer have to worry” about viruses.
I have to marvel, though, over human ingenuity. That so many people would be so dedicated to annoying total strangers by discovering new ways of intruding into their lives never ceases to amaze me.
But I guess things could be worse. At least these hackers aren’t going out and getting government jobs….
