Mandriva Linux Security Advisory : krb5 (MDVSA-2010:245)

This script is Copyright (C) 2010-2013 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

A vulnerability was discovered and corrected in krb5 :

An unauthenticated remote attacker could alter a SAM-2 challenge,
affecting the prompt text seen by the user or the kind of response
sent to the KDC. Under some circumstances, this can negate the
incremental security benefit of using a single-use authentication
mechanism token. An unauthenticated remote attacker has a 1/256 chance
of forging KRB-SAFE messages in an application protocol if the
targeted pre-existing session uses an RC4 session key. Few application
protocols use KRB-SAFE messages (CVE-2010-1323).

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:
