U radu programskog paketa logrotate, namijenjenog operacijskom sustavu Fedora 14, uočena su tri sigurnosna propusta. Riječ je o alatu koji pojednostavljuje upravljanje višestrukim log datotekama, omogućujući automatsku izmjenu, kompresiju, uklanjanje te slanje log datoteka. Propusti su posljedica nepravilnosti u radu funkcija "shred_file", "writeState" i "createOutputFile" u datoteci "logrotate.c". Napadaču omogućuju izvođenje DoS napada, pokretanje proizvoljnih naredbi te čitanje log datoteka. Korisnike se potiče na nadogradnju.
