Vulnerability Assessment Details

MDKSA-2004:056-1: 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 MDKSA-2004:056-1 (krb5).

Multiple buffer overflows exist in the krb5_aname_to_localname() library
function that if exploited could lead to unauthorized root rights. In order
to exploit this flaw, a possible hacker must first successfully authenticate to a
vulnerable service, which must be configured to enable the explicit mapping or
rules-based mapping functionality of krb5_aname_to_localname, which is not a
default configuration.
Mandrakesoft encourages all users to upgrade to these patched krb5 packages.
Update:
The original patch provided contained a bug where rule-based entries on systems
without HAVE_REGCOMP would not work. These updated packages provide the second
patch provided by Kerberos development team which fixes that behaviour.
