Debian DSA-1473-1 : scponly - design flaw

high Nessus Plugin ID 30065

Synopsis

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

Description

Joachim Breitner discovered that Subversion support in scponly is inherently insecure, allowing execution of arbitrary commands. Further investigation showed that rsync and Unison support suffer from similar issues. This set of issues has been assigned CVE-2007-6350.

In addition, it was discovered that it was possible to invoke scp with certain options that may lead to the execution of arbitrary commands (CVE-2007-6415 ).

This update removes Subversion, rsync and Unison support from the scponly package, and prevents scp from being invoked with the dangerous options.

Solution

Upgrade the scponly package.

For the old stable distribution (sarge), these problems have been fixed in version 4.0-1sarge2.

For the stable distribution (etch), these problems have been fixed in version 4.6-1etch1.
