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

Low Nessus Plugin ID 50848


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


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: 90
