(Debian Issues Fix) CVS Server Piped Checkout Input Validation Flaw Discloses RCS Files to Remote Authenticated Users
SecurityTracker Alert ID:  1009854
SecurityTracker URL:  http://securitytracker.com/id/1009854
CVE Reference:   CVE-2004-0405   (Links to External Site)
Date:  Apr 19 2004
Impact:   Disclosure of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 1.11.15
Description:   A vulnerability was reported in CVS. A remote authenticated user may be able to view arbitrary RCS files on the server.

It is reported that a remote authenticated user can invoke a piped checkout of paths above $CVSROOT to view the contents of RCS archive files anywhere on a CVS server. This flaw can reportedly be triggered using relative pathnames containing the '../' directory traversal strings.

Debian credited Derek Robert Price with discovering this flaw.

Impact:   A remote authenticated user can view RCS files located anywhere on the target system.
Solution:   Debian has released a fix for the current stable distribution (woody) in version 1.11.1p1debian-9woody2.

Debian GNU/Linux 3.0 alias woody:

- --------------------------------------------------------------------------

Package        : cvs
Vulnerability  : several
Problem-Type   : remote
Debian-specific: no
CVE Ids        : CAN-2004-0180 CAN-2004-0405

Two vulnerabilities have been discovered and fixed in CVS:

 CAN-2004-0180 - Sebastian Krahmer discovered a vulnerability whereby
 a malicious CVS pserver could create arbitary files on the client
 system during an update or checkout operation, by supplying absolute
 pathnames in RCS diffs.

 CAN-2004-0405 - Derek Robert Price discovered a vulnerability whereby
 a CVS pserver could be abused by a malicious client to view the
 contents of certain files outside of the CVS root directory using
 relative pathnames containing "../".

For the current stable distribution (woody) these problems have been
fixed in version 1.11.1p1debian-9woody2.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you update your cvs package.

Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
