Debian DSA-969-1 : scponly - design error

high Nessus Plugin ID 22835

Synopsis

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

Description

Max Vozeler discovered a vulnerability in scponly, a utility to restrict user commands to scp and sftp, that could lead to the execution of arbitrary commands as root. The system is only vulnerable if the program scponlyc is installed setuid root and if regular users have shell access to the machine.

Solution

Upgrade the scponly package.

The old stable distribution (woody) does not contain an scponly package.

For the stable distribution (sarge) this problem has been fixed in version 4.0-1sarge1.
