[SECURITY] Fedora Core 1 Update: krb5-1.3.3-6



---------------------------------------------------------------------
Fedora Update Notification
FEDORA-2004-149
2004-06-04
---------------------------------------------------------------------

Product     : Fedora Core 1
Name        : krb5
Version     : 1.3.3                      
Release     : 6                  
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.

---------------------------------------------------------------------
Update Information:

Bugs have been fixed in the krb5_aname_to_localname library function.
Specifically, buffer overflows were possible for all Kerberos
versions up to and including 1.3.3. The krb5_aname_to_localname
function translates a Kerberos principal name to a local account
name, typically a UNIX username.  This function is frequently used
when performing authorization checks.

If configured with mappings from particular Kerberos principals to
particular UNIX user names, certain functions called by
krb5_aname_to_localname will not properly check the lengths of
buffers used to store portions of the principal name. If configured
to map principals to user names using rules, krb5_aname_to_localname
would consistently write one byte past the end of a buffer allocated
from the heap. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0523 to this issue.

Only configurations which enable the explicit mapping or rules-based
mapping functionality of krb5_aname_to_localname() are vulnerable.
These configurations are not the default.
