If the missing format string is variable and controlled externally (e.g. 
if read from a file or from network communication), please file it 
with RC severity and the security tag. (If it's a popular Perl module, 
please contact  team at security.debian.org, so that we can coordinate with 
other distros.)

Otherwise it's rather "normal" severity.
