medium Nessus Plugin ID 22789

Synopsis

The remote Debian host is missing a security-related update.

Description

A buffer overflow has been discovered in dropbear, a lightweight SSH2 server and client, that may allow authenticated users to execute arbitrary code as the server user (usually root).

The old stable distribution (woody) does not contain dropbear packages.

For the stable distribution (sarge) this problem has been fixed in version 0.45-2sarge0.
