# IDA-Pro 5.4: old bugs on the new streets (was: to download or to not download)
Posted in IDA-Pro, bugs, win32 on 02/01/2009 02:26 pm by kpncIDA-Pro 5.4 has been released. aside of many positive changes it’s just a huge bug-fix. take the old bug with zero-based PE-files for example. I reported it to Ilfak long before 5.3. now it’s fixed and following pictures taken by Elias Bachaalany (the clever guy working for hex-rays) proves it.
not good for me, coz I was going to talk about it (and many other IDA-Pro bugs) on Code Gate 2009 security conference in South Korea . well, never mind. I have enough time to redesign my syllabus

dead bug
TLS flooding bug (also discovered by nezumi) has not been fixed yet. um, going to write a short article how to fix it with _your_ hands.
