Hi,
Besides my K4NT, now I have a PW3 with 5.6.5. While waiting for BranchDelay to release his JailBreak, I couldn't find a place where efforts are coordinated in order to find new JB vectors, internal useful commands, ...
So I thought about a new thread for that, but also found potential reasons not to do it like:
- Making public new JB exploitable vectors can help lab126 close them so we cannot resort to them in future versions
- The idea is good, but a thread is not the right tool, better use the wiki
So I'm asking your opinion about the idea.
This is an example of the kind of info we could consolidate:
Everyone says that 5.6.5 and 5.6.1.1 are "equally jailbreakable", but the gpl sources from amazon show some differences.
gtk/gdk-pixbuf/io-png.c was modified with changes from
Code:
longjmp (png_save_ptr->jmpbuf, 1);
to
Code:
longjmp (png_jmpbuf(png_save_ptr), 1);
A search shows that such changes were in order to "
make the png loader compatible with libpng 1.5"
Could this be used to jailbreak via a carefully crafted PNG file ?. Most probably not; but I'd advise anyone that still has 5.6.1.1
NOT
to upgrade to 5.6.5 until a JB is made public.
