Seriously? *Another* PDF Vulnerability?

Right, listen up you lot. Some idiot found a flaw in how pdf-parser handles streams within PDFs. Apparently, if a PDF is crafted just so – and let’s be honest, it will be by some script kiddie looking for attention – it can cause a denial of service. Basically, the parser gets stuck in an infinite loop trying to process a maliciously formatted stream object. It’s not like it *tries* to handle things correctly, no. Just chugs along until it pukes.

The affected versions are all over the place: pdf-parser 0.1.4 and earlier. If you’re using this library (and frankly, why would you be?), update immediately. Like, *now*. Don’t wait for a zero-day exploit to ruin your day. The fix is simple enough – they added some sanity checks on stream lengths. Groundbreaking stuff, really.

There’s no remote code execution here, thankfully. Just a DoS. Still annoying as hell though. And you *know* this will be weaponized within 24 hours. Expect to see it in phishing emails and drive-by downloads faster than you can say “buffer overflow.”

Honestly, PDFs are just the worst. A security nightmare wrapped in a portability convenience package.

Related Anecdote: Back in ’07, I had a user who insisted on converting *everything* to PDF. Spreadsheets, source code, even freaking text files. Then he complained his computer was slow. Turns out he’d created a 50MB PDF of a single paragraph email. I swear, some people just ask for trouble. And then they blame *me*.
