Ytterligare information:

Det upptäcktes att GnuPG 2 använde en frisläppt pekare vid verifiering av en signatur eller vid import av ett certifikat med flera Subject Alternate Names. Detta kunde möjligen leda till exekvering av godtycklig kod.

För den stabila utgåvan (Lenny) har detta problem rättats i version 2.0.9-3.1+lenny1.

För den instabila utgåvan (Sid) har detta problem rättats i version 2.0.14-2.

GnuPG 1 (i paketet gnupg) påverkas inte av detta problem.

Vi rekommenderar att ni uppgraderar era gnupg2-paket.
