The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2012-29:01 advisory.

    Kerberos V5 is a trusted-third-party network authentication system, which can improve your network's     security by eliminating the insecure practice of cleartext passwords.
    Security issues fixed with this release:
    CVE-2011-1527     The kdb_ldap plugin in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.9 through 1.9.1,     when the LDAP back end is used, allows remote attackers to cause a denial of service (NULL pointer     dereference and daemon crash) via a kinit operation with incorrect string case for the realm, related to     the is_principal_in_realm, krb5_set_error_message, krb5_ldap_get_principal, and process_as_req functions.
    CVE-2011-1528     The krb5_ldap_lockout_audit function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8     through 1.8.4 and 1.9 through 1.9.1, when the LDAP back end is used, allows remote attackers to cause a     denial of service (assertion failure and daemon exit) via unspecified vectors, related to the     locked_check_p function. NOTE: the Berkeley DB vector is covered by CVE-2011-4151.
    CVE-2011-1529     The lookup_lockout_policy function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8     through 1.8.4 and 1.9 through 1.9.1, when the db2 (aka Berkeley DB) or LDAP back end is used, allows     remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that     trigger certain process_as_req errors.
    CVE-2011-1530     The process_tgs_req function in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka     krb5) 1.9 through 1.9.2 allows remote authenticated users to cause a denial of service (NULL pointer     dereference and daemon crash) via a crafted TGS request that triggers an error other than the     KRB5_KDB_NOENTRY error.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version MAIN 6.06, has krb5 packages installed that are affected by multiple vulnerabilities:

  - plugins/preauth/pkinit/pkinit_crypto_openssl.c in MIT Kerberos 5 (aka krb5) through 1.15.2 mishandles     Distinguished Name (DN) fields, which allows remote attackers to execute arbitrary code or cause a denial     of service (buffer overflow and application crash) in situations involving untrusted X.509 data, related     to the get_matching_data and X509_NAME_oneline_ex functions. NOTE: this has security relevance only in use     cases outside of the MIT Kerberos distribution, e.g., the use of get_matching_data in KDC certauth plugin     code that is specific to Red Hat. (CVE-2017-15088)

  - The process_chpw_request function in schpw.c in the password-changing functionality in kadmind in MIT     Kerberos 5 (aka krb5) 1.7 through 1.9 frees an invalid pointer, which allows remote attackers to execute     arbitrary code or cause a denial of service (daemon crash) via a crafted request that triggers an error     condition. (CVE-2011-0285)

  - 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 (1) ftpd and (2) ksu programs in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, and (b)     Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which might allow local users to     gain privileges by causing setuid to fail to drop privileges. NOTE: as of 20060808, it is not known     whether an exploitable attack scenario exists for these issues. (CVE-2006-3084)

  - The RPC library in Kerberos 5 1.4 through 1.4.4, and 1.5 through 1.5.1, as used in Kerberos administration     daemon (kadmind) and other products that use this library, calls an uninitialized function pointer in     freed memory, which allows remote attackers to cause a denial of service (crash) and possibly execute     arbitrary code via unspecified vectors. (CVE-2006-6143)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Multiple vulnerabilities has been found and corrected in krb5 :

The kdb_ldap plugin in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.9 through 1.9.1, when the LDAP back end is used, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a kinit operation with incorrect string case for the realm, related to the is_principal_in_realm, krb5_set_error_message, krb5_ldap_get_principal, and process_as_req functions (CVE-2011-1527).

The krb5_ldap_lockout_audit function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8 through 1.8.4 and 1.9 through 1.9.1, when the LDAP back end is used, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via unspecified vectors, related to the locked_check_p function (CVE-2011-1528).

The lookup_lockout_policy function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8 through 1.8.4 and 1.9 through 1.9.1, when the db2 (aka Berkeley DB) or LDAP back end is used, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that trigger certain process_as_req errors (CVE-2011-1529).

The updated packages have been patched to correct these issues.

This update applies the upstream patch to fix a NULL pointer dereference wi= th the LDAP kdb backend (CVE-2011-1527), an assertion failure with multiple= kdb backends (CVE-2011-1528), and a NULL pointer dereference with multiple= kdb backends (CVE-2011-1529).
