Eric Romang discovered that xpvm, a graphical console and monitor for
PVM, creates a temporary file that allows local attackers to create or
overwrite arbitrary files with the privileges of the user running
xpvm.
For the old stable distribution (woody) this problem has been fixed in
version 1.2.5-7.2woody1.
For the stable distribution (sarge) this problem has been fixed in
version 1.2.5-7.3sarge1.

We recommend that you upgrade your xpvm package.
