The affected releases listed for this advisory state &quot;Known Affected Releases: (4) 4.2(8), 5.2(9), 6.1(5), 6.2(10)&quot; Our 7Ks are running 6.1(2), does this mean that any code in the 6.1(x) release below 6.1(5) is affected? Or is it just 6.1(5) specifically and none other running 6.1(x)?   Thanks, Jim
