CERT-SE:s veckobrev v.44

Denna vecka har i hög grad präglats av bevakningen av sårbarheter i OpenSSL. Sårbarheterna bedömdes slutligen som allvarliga och CERT-SE rekommenderar att uppdatera sårbara system så snart som möjligt samt att se över vilka programvaror som den egna organisationen använder som kan vara påverkade.

Trevlig helg önskar CERT-SE!
