BTW I only filed this as important as the only application in Debian which 
seems to use this lib is dsniff and in this case it's not really an important 
issue.

This doesn't warrant a DSA, but you could still fix this through a stable 
point update. If you want to do this, please get in touch with the stable
release managers: <debian-release@lists.debian.org>.

Cheers,

There was a mistake on the CVE id assignment, please do not refer to this bug 
using CVE-2010-1144 but CVE-2010-0751 instead.
