 UNIRAS (UK Government CERT) Briefing - 773/06 dated 27.11.06 time 14:55

 Co-ordination Centre)

Title
=====

Two Mandriva Security Advisories:

1. MDKA-2006:054 - Updated dbus packages fix D-Bus specification compliance

2. MDKSA-2006:218 - Updated apache-mod_auth_kerb packages fixes DoS vulnerability

Detail
======

1.  On Mandriva Linux 2007.0, the path for D-Bus system bus socket was not
 following D-Bus specification.  This could cause some implementation of
 the D-Bus specification to not detect the system bus correctly.  This
 updated package ensures the location of the system bus is exported
 through DBUS_SYSTEM_BUS_ADDRESS, in compliance with D-Bus
 specification.

2.  An off-by-one error in the der_get_oid function in mod_auth_kerb 5.0
 allows remote attackers to cause a denial of service (crash) via a
 crafted Kerberos message that triggers a heap-based buffer overflow in
 the component array.
