Mandriva Linux Security Advisory : krb5 (MDVSA-2009:082)

Medium Nessus Plugin ID 36535


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


The spnego_gss_accept_sec_context function in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.6.3, when SPNEGO is used, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via invalid ContextFlags data in the reqFlags field in a negTokenInit token (CVE-2009-0845).

This update provides the fix for that security issue.


Update the affected packages.
