Fedora Core 2 2004-563: krb5

Vulnerability Assessment Summary Check for the version of the krb5 package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory FEDORA-2004-563 (krb5). 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 permit 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 CVE-2004-1189 to this issue. Additionally a temporary file bug was found in the Kerberos krb5-send-pr command. It is possible that a possible hacker could create a specially crafted temporary file that could permit 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 CVE-2004-0971 to this issue. * Mon Dec 20 2004 Nalin Dahyabhai 1.3.6-1 - update to 1.3.6, which includes the previous fix * Mon Dec 20 2004 Nalin Dahyabhai 1.3.5-8 - apply fix from Tom Yu for MITKRB5-SA-2004-004 (CVE-2004-1189) * Fri Dec 17 2004 Martin Stransky 1.3.5-7 - fix deadlock during file transfer via rsync/krsh - thanks goes to James Antil for hint * Fri Nov 26 2004 Nalin Dahyabhai 1.3.5-6 - rebuild * Mon Nov 22 2004 Nalin Dahyabhai 1.3.5-3 - fix predictable-tempfile-name bug in krb5-send-pr (CVE-2004-0971, #140036) * Tue Nov 16 2004 Nalin Dahyabhai - silence compiler warning in kprop by using an in-memory ccache with a fixed name instead of an on-disk ccache with a name generated by tmpnam() * Tue Nov 16 2004 Nalin Dahyabhai 1.3.5-2 - fix globbing patch port mode (#139075) * Mon Nov 01 2004 Nalin Dahyabhai 1.3.5-1 - fix segfault in telnet due to incorrect checking of gethostbyname_r result codes (#129059) * Fri Oct 15 2004 Nalin Dahyabhai - remove rc4-hmac:norealm and rc4-hmac:onlyrealm from the default list of supported keytypes in kdc.conf - they produce exactly the same keys as rc4-hmac:normal because rc4 string-to-key ignores salts - nuke kdcrotate - there are better ways to balance the load on KDCs, and the SELinux policy for it would have been scary-looking - update to 1.3.5, mainly to include MITKRB5SA 2004-002 and 2004-003 * Tue Aug 31 2004 Nalin Dahyabhai 1.3.4-7 - rebuild * Tue Aug 24 2004 Nalin Dahyabhai 1.3.4-6 - rebuild Solution : http://www.fedoranews.org/blog/index.php?p=218 Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: This script is Copyright (C) 2004 Tenable Network Security
