Mandrake Security Advisory MDVSA-2009:082 (krb5)

The remote host is missing an update to krb5 announced via advisory MDVSA-2009:082.
To upgrade automatically use MandrakeUpdate or urpmi. The verification of md5 checksums and GPG signatures is performed automatically for you.
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. Affected: 2008.0, 2008.1, 2009.0
