Yderligere oplysninger:

Man opdagede at GnuPG 2 anvendte en frigivet pointer, når en signatur blev verificeret eller der blev importeret et certifikat med mange Subject Alternate Names, hvilket potentielt kunne føre til udførelse af vilkårlig kode.

I den stabile distribution (lenny), er dette problem rettet i version 2.0.9-3.1+lenny1.

I den ustabile distribution (sid), er dette problem rettet i version 2.0.14-2.

GnuPG 1 (i gnupg-pakken) er ikke påvirket af dette problem.

Vi anbefaler at du opgraderer dine gnupg2-pakker.
