Debian Security Advisory

DSA-352-1 fdclone -- insecure temporary directory

Date Reported:

22 Jul 2003

Affected Packages:

fdclone

Vulnerable:

Yes

Security database references:

In the Bugtraq database (at SecurityFocus): BugTraq ID 8247.
In Mitre's CVE dictionary: CVE-2003-0596.

More information:

fdclone creates a temporary directory in /tmp as a workspace. However, if this directory already exists, the existing directory is used instead, regardless of its ownership or permissions. This would allow an attacker to gain access to fdclone's temporary files and their contents, or replace them with other files under the attacker's control.

For the stable distribution (woody) this problem has been fixed in version 2.00a-1woody3.

For the unstable distribution (sid) this problem has been fixed in version 2.04-1.

We recommend that you update your fdclone package.

Fixed in:

Debian GNU/Linux 3.0 (woody)
