Fedora Update Notification
FEDORA-2004-563
2004-12-21
---------------------------------------------------------------------

Product     : Fedora Core 2
Name        : krb5
Version     : 1.3.6
Release     : 1
Summary     : The Kerberos network authentication system.
Description :
Kerberos V5 is a trusted-third-party network authentication system,
which can improve your network's security by eliminating the insecure
practice of cleartext passwords.

A heap based buffer overflow bug was found in the administration
library of Kerberos 1.3.5 and earlier.  This overflow in the password
history handling code could allow an authenticated remote attacker to
execute commands on a realm's master Kerberos KDC.  The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2004-1189 to this issue.

Additionally a temporary file bug was found in the Kerberos
krb5-send-pr command.  It is possible that an attacker could create a
specially crafted temporary file that could allow an arbitrary file
to be overwritten which the victim has write access to.  The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2004-0971 to this issue.

Fedora: krb5-1.3.6-1 update

December 21, 2004
A heap based buffer overflow bug was found in the administration library of Kerberos 1.3.5 and earlier

Summary

Kerberos V5 is a trusted-third-party network authentication system,

which can improve your network's security by eliminating the insecure

practice of cleartext passwords.

A heap based buffer overflow bug was found in the administration

library of Kerberos 1.3.5 and earlier. This overflow in the password

history handling code could allow an authenticated remote attacker to

execute commands on a realm's master Kerberos KDC. The Common

Vulnerabilities and Exposures project (cve.mitre.org) has assigned

the name CAN-2004-1189 to this issue.

Additionally a temporary file bug was found in the Kerberos

krb5-send-pr command. It is possible that an attacker could create a

specially crafted temporary file that could allow an arbitrary file

to be overwritten which the victim has write access to. The Common

Vulnerabilities and Exposures project (cve.mitre.org) has assigned
