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. http://marc.theaimsgroup.com/?l=full-disclosure&m=113342788118630&w=2 Doesn't Affec: RHEL2.1 This issue also affects RHEL3
