U radu besplatnog antivirusnog alata clamav, koji se koristi na Linux sustavima za pregled privitaka elektroničke pošte, otkrivena su dva propusta. Prvi propust je rezultat preljeva međuspremnika u funkciji "cli_pdf" u datoteci "libclamav/pdf.c", a može se iskoristiti za DoS napad podmetanjem posebno oblikovanog PDF dokumenta. Drugi se javlja u funkciji "ba_read_project_strings" u "vba_extract.c", a moguće ga je iskoristiti udaljeno za pokretanje proizvoljnog programskog koda s posebno oblikovanim VBA (eng. Visual Basic for Applications) podacima. Korisnike se potiče na korištenje dostupne nadogradnje.
