U radu programskog paketa Subversion, namijenjenom konkurentnom održavanju programskog koda, web stranica i dokumentacije (CVS), otkriven je jedan sigurnosni propust. Propust je pronađen u "mod_dav_svn" modulu gdje dolazi do derefenciranja NULL pokazivača ukoliko se pošalje posebno oblikovana značka u HTTP zahtjevu od klijenta koji nije autenticiran na poslužitelju. Rezultat iskorištavanja propusta je udaljeno izvođenje DoS (eng. Denial of Service) napada. Korisnicima se savjetuje korištenje dostupne nadogradnje.
