Re: [Full-disclosure] Breaking the links: Exploiting the linker

CVEs have now been assigned to the two previously reported bugs as follows:

1)  http://www.nth-dimension.org.uk/downloads.php?id=83 - Privesc attack
using DB2 from normal user to root, the PoC is for Linux but based on
testing the AIX version looks iffy too although I couldn't get gcc to
generate a valid library to exploit it.

CVE-2011-4061.  FWIW I now have a version of the exploit for this working on 
AIX, based on a copy of kbbacf1 from IBM Tivoli Monitoring  It 
therefore appears that the vulnerable version of kbbacf1 isn't just shipped 
with DB2.

2) http://www.nth-dimension.org.uk/downloads.php?id=80 - Generic attack on
the QNX runtime linker which abuses an arbitrary file overwrite and race
condition to get root.
