RHBA-2013:1555 - cvs bug fix and enhancement update

Synopsis

cvs bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated cvs packages that fix one bug and add one enhancement are now available for Red Hat Enterprise Linux 6.

Description

The Concurrent Versions System (CVS) is a version control system that can record the history of your files. CVS only stores the differences between versions, instead of every version of every file you have ever created. CVS also keeps a log of who, when, and why changes occurred.

This update fixes the following bug:

• When a CVS client tried to establish a GSSAPI-authenticated connection to a DNS load-balanced cluster node, the authentication failed because each node had a unique host name. With this update, the GSSAPI CVS server has been modified to search for any Kerberos key that matches the "cvs" service and any host name. As a result, the CVS server can now authenticate clients using GSSAPI even if the server's host name does not match the domain name, and thus Kerberos principal host name part, common for all cluster nodes. CVS server administrators are advised to deploy two Kerberos principals to each node: a principal matching the node's host name and a principal matching the cluster's domain name. (BZ#671460)

In addition, this update adds the following enhancement:

• Previously, the CVS server did not pass the client address to the Pluggable Authentication Modules (PAM) system. As a consequence, it was not possible to distinguish clients by the network address with the PAM system and the system was not able to utilize the client address for authentication or authorization purposes. With this update, the client network address is passed to the PAM subsystem as a remote host item (PAM_RHOST). Also, the terminal item (PAM_TTY) is set to a dummy value "cvs" because some PAM modules cannot work with an unset value. (BZ#684789)

Users of cvs are advised to upgrade to these updated packages, which fix this bug and add this enhancement.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
