Advisory: RHSA-2003:020-10
Type: Security Advisory
Severity: N/A
Issued on: 2003-01-31
Last updated on: 2003-01-31
Affected Products: Red Hat Linux 6.2
Red Hat Linux 7.0
Red Hat Linux 7.1
Red Hat Linux 7.2
Red Hat Linux 7.3
Red Hat Linux 8.0
CVEs (cve.mitre.org): CVE-2003-0041

Details

Updated packages fix a vulnerability found in the Kerberos ftp client
distributed with the Red Hat Linux krb5 packages.

Kerberos is a network authentication system.

A problem has been found in the Kerberos ftp client. When retrieving a
file with a filename beginning with a pipe character, the ftp client will
pass the filename to the command shell in a system() call. This could
allow a malicious ftp server to write to files outside of the current
directory or execute commands as the user running the ftp client.

The Kerberos ftp client runs as the default ftp client when the Kerberos
package krb5-workstation is installed on a Red Hat Linux distribution.

All users of Kerberos are advised to upgrade to these errata packages which
contain a backported patch and are not vulnerable to 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.
