sup - insecure temporary file

sup, a package used to maintain collections of files in identical
versions across machines, fails to take appropriate security
precautions when creating temporary files. A local attacker could
exploit this vulnerability to overwrite arbitrary files with the
privileges of the user running sup.

For the stable distribution (woody) this problem has been fixed in
version 1.8-8woody1.

For the unstable distribution (sid) this problem has been fixed in
version 1.8-9.

We recommend that you update your sup package.
