Beskrivelse:
Der er rapporteret en sårbarhed i Python, som kan udnyttes af ondsindede personer til at udføre et DoS (Denial of Service) og potentielt kompromittere et sårbart system.

Sårbarheden skyldes en fejl under håndteringen af UTF32/UCS-4 indkodede strenge i "repr()" funktionen. Hvis en applikation benytter denne funktion til at behandle bruger-suppleret input, kan dette potentielt udnyttes til at eksekvere vilkårlig kode.

Løsning:
Opdater til version 2.5.

Rapporteret af / Kredit:
Benjamin C. Wiley Sittler
