U radu programskog paketa proftpd-dfsg uočena su tri nova sigurnosna nedostatka. Radi se o programu za sigurnu i jednostavnu razmjenu podataka u mreži pomoću FTP (eng. File Transfer Protocol) protokola. Prvi nedostatak vezan je uz neispravnu obradu tzv. "ABOR" naredbi, drugi proizlazi iz ranjivosti koja omogućuje injekciju SQL koda preko modula "mod_sql", a treći je uzrokovan tzv. "directory traversal" ranjivošću modula "mod_site_misc". Udaljeni, zlonamjerni korisnici mogu iskoristiti navedene ranjivosti za pokretanje napada uskraćivanja usluge, izvršavanje vlastitog programskog koda te pristup osjetljivim datotekama i njihovu izmjenu. Svim se korisnicima savjetuje nadogradnja paketa.
