Oracle Solaris Third-Party Patch Update : kerberos (cve_2002_2443_denial_of)

This script is Copyright (C) 2015 Tenable Network Security, Inc.


Synopsis :

The remote Solaris system is missing a security patch for third-party
software.

Description :

The remote Solaris system is missing necessary patches to address
security updates :

- schpw.c in the kpasswd service in kadmind in MIT
Kerberos 5 (aka krb5) before 1.11.3 does not properly
validate UDP packets before sending responses, which
allows remote attackers to cause a denial of service
(CPU and bandwidth consumption) via a forged packet that
triggers a communication loop, as demonstrated by
krb_pingpong.nasl, a related issue to CVE-1999-0103.
(CVE-2002-2443)

- The pkinit_server_return_padata function in
plugins/preauth/pkinit/pkinit_srv.c in the PKINIT
implementation in the Key Distribution Center (KDC) in
MIT Kerberos 5 (aka krb5) before 1.10.4 attempts to find
an agility KDF identifier in inappropriate
circumstances, which allows remote attackers to cause a
denial of service (NULL pointer dereference and daemon
crash) via a crafted Draft 9 request. (CVE-2012-1016)

- The pkinit_check_kdc_pkid function in
plugins/preauth/pkinit/ pkinit_crypto_openssl.c in the
PKINIT implementation in the Key Distribution Center
(KDC) in MIT Kerberos 5 (aka krb5) before 1.10.4 and
1.11.x before 1.11.1 does not properly handle errors
during extraction of fields from an X.509 certificate,
which allows remote attackers to cause a denial of
service (NULL pointer dereference and daemon crash) via
a malformed KRB5_PADATA_PK_AS_REQ AS-REQ request.
(CVE-2013-1415)
