Mandriva: Updated Kerberos packages fix multiple Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Mandrake A flaw was discovered in how the Kerberos krb5kdc handled Kerberos v4 protocol packets. An unauthenticated remote attacker could use this flaw to crash the krb5kdc daemon, disclose portions of its memory, or possibly %execute arbitrary code using malformed or truncated Kerberos v4 protocol requests (CVE-2008-0062, CVE-2008-0063).

 Package : krb5
 Date    : March 19, 2008
 Affected: Corporate 3.0, Multi Network Firewall 2.0

 Problem Description:
 
 A flaw was discovered in how the Kerberos krb5kdc handled Kerberos v4
 protocol packets.  An unauthenticated remote attacker could use this
 flaw to crash the krb5kdc daemon, disclose portions of its memory,
 or possibly %execute arbitrary code using malformed or truncated
 Kerberos v4 protocol requests (CVE-2008-0062, CVE-2008-0063).
 
 This issue only affects krb5kdc when it has Kerberos v4 protocol
 compatibility enabled, which is a compiled-in default in all
 Kerberos versions that Mandriva Linux ships prior to Mandriva
 Linux 2008.0.  Kerberos v4 protocol support can be disabled by
 adding v4_mode=none (without quotes) to the [kdcdefaults] section
 of /etc/kerberos/krb5kdc/kdc.conf.
 
 The updated packages have been patched to correct these issues.
