Thanks. I have taken a look at this. I have noticed the regression you mentioned
on the pu bugs, and so I have tried to backport the termcap-fix.diff.
Unfortunately most hunks fail to apply, and applying it manually I noticed the
code has changed quite a bit, and as I don't know the code well, I'm worried we
may not fix the regression properly or we may cause other issues.
I wanted to get this fixed as it will be fixed in stretch and jessie, and we
don't have a wheezy-proposed-updates suite, and given the comments from the
reporter about one bug leading to arbitrary code execution. But given the risk
of not fixing this properly, the few users of the library, the disputed severity
of that bug, and that this was tagged no-dsa in the first place, I'm tempted to
do that for wheezy too and move on.
