+++ This bug was initially created as a clone of Bug #174683 +++

Perl integer overflow issue

There exists an integer overflow problem in Perl which can lead to a
string format issue.  If a large enough integer is supplied to a
printf statement which uses the %n conversion, it may be possible to
execute arbitrary code.  This problem will not be easy to remotely
exploit as a very poorly written script will first be needed.
