Package: xterm
Version: 6.8.2.dfsg.1-7
Severity: important

As shown by strace -f, "xterm -e ./cmd" tries to access cmd found in
$PATH (ignoring ".") instead of cmd found in the current directory.

If cmd isn't found, xterm just segfaults. In particular, this breaks
rox, which tries to compile in an xterm with a command of the form
"xterm -e ./relative_path_to/AppRun --compile".

If cmd is found, fortunately xterm doesn't seem to try to execute
this program (this would have been a security hole), but executes
the correct one.
