RHBA-2005:447 - Bug Fix Advisory

Topic

Updated cdrtools packages that fix a possible exploit are now available for
Red Hat Enterprise Linux 3.

Description

Cdrecord is an application for recording audio and data CDs. Cdrecord
works with many different brands of CD recorders, fully supports
multi-sessions, and provides human-readable error messages.

The cdrecord package on Red Hat Enterprise Linux does not require setuid
root for use by normal users. The permissions of the writer device are
changed by pam_console_apply at console login. Setting the uid of cdrecord
to root opens a vulnerability to possible exploitation.

All users of cdrecord that setuid root should upgrade to these updated
packages, which resolve this issue.

Solution

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
