Yderligere oplysninger:

Der er opdaget en fejl i OpenSSHs bufferhåndtering, hvor en buffer kunne blive markeret som forøget, når den faktiske gen-allokering fejlede.

DSA-382-2:

Denne bulletin er et tillæg til den tidligere bulletin DSA-382-1: Yderligere to bufferhåndteringsproblemer er fundet foruden det problem, som er beskrevet i DSA-382-1. Det vides ikke om disse fejl kan udnyttes, men som en sikkerhedsforanstaltning anbefales det at opgradere.

DSA-382-3:

Denne bulletin er et tillæg til den tidligere bulletin DSA-382-1 og DSA-382-2: Solar Design har fundet yderligere fire fejl i OpenSSH, som måske kan udnyttes.
