The Asterisk Development Team has announced security releases for Asterisk

The releases of Asterisk 1.4.39.2, 1.6.1.22, 1.6.2.16.2, and 1.8.2.4 resolve an
issue that when decoding UDPTL packets, multiple stack and heap based arrays can

T.38 pass through or termination are vulnerable. The issue and resolution are
described in the AST-2011-002 security advisory.

Ishfaq, I spoke to soon and was looking at the wrong checkout.  The
1.8.2.4 does NOT have the patch from issue 18403.  Asterisk Branch
1.8.3 does have the patch which happened just 1 day after the 1.8.2.4
release. I must have lost the release email because I can only find
the tag in SVN.  I was confused and hope I did not cause you any
confusion.
