Re: Solaris libc exploit

4118295 LC_* can be used to obtain root access from setuid programs
This is already fixed in Solaris 7 and the following patches for
Solaris 2.6:
  5.6         i386  105211-06
  5.6         sparc 105210-06

OK, did I miss the later messages on this topic?  I've been waiting for a
formal announcement from Sun, or a real patch, or someone to say that this
patch definitely fixes the problem, or SOMETHING...

I don't know what version of patching Peter was talking about, but right
now, I can consistently gain root on my Solaris 7 sparc box, with MU2
applied, using the LC_MESSAGES buffer overflow exploit.  And I can
consistently do Bad Things to sh on a Solaris 2.6 box with 105210-19
(its a production machine, I can't actively root it).

I'm praying I missed something.  Did I?
