Beskrivelse:
Der er rapporteret nogle sårbarheder i Clam AntiVirus, hvor den ene har ukendt betydning og de andre kan udnyttes af ondsindede personer til at udføre et DoS (Denial of Service) eller kompromittere et sårbart system.

1) En uspecificeret "file descriptor" læk eksisterer i libclamav/chmunpack.c.

2) En "signedness" fejl i funktionen "cab_unstore()" i libclamav/cab.c kan udnyttes til at forårsage et stack-baseret buffer overflow via en specielt udformet ".cab" fil og muliggør eksekvering af vilkårlig kode.

3) En "file descriptor" læk i libclamav/pdf.c under håndteringen af PDF-filer med tomme objekter kan potentielt udnyttes til at udføre et DoS ved at lokke et automatiseret system til at håndtere en specielt udformet PDF-fil.

Løsning:
Opdatér til version 0.90.2.
