The krb5_ldap_get_password_policy_from_dn function in plugins/kdb/ldap/libkdb_ldap/ldap_pwd_policy.c in MIT Kerberos 5 (aka krb5) before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service (daemon crash) via a successful LDAP query with no results, as demonstrated by using an incorrect object type for a password policy.

Kerberos, a system for authenticating users and services on a network, was affected by several vulnerabilities. The Common Vulnerabilities and Exposures project identifies the following issues.

CVE-2013-1418 Kerberos allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request when multiple realms are configured.

CVE-2014-5351 Kerberos sends old keys in a response to a -randkey
-keepold request, which allows remote authenticated users to forge tickets by leveraging administrative access.

CVE-2014-5353 When the KDC uses LDAP, allows remote authenticated users to cause a denial of service (daemon crash) via a successful LDAP query with no results, as demonstrated by using an incorrect object type for a password policy.

CVE-2014-5355 Kerberos expects that a krb5_read_message data field is represented as a string ending with a '\0' character, which allows remote attackers to (1) cause a denial of service (NULL pointer dereference) via a zero-byte version string or (2) cause a denial of service (out-of-bounds read) by omitting the '\0' character,

CVE-2016-3119 Kerberos allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request to modify a principal.

CVE-2016-3120 Kerberos allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an S4U2Self request.

For Debian 7 'Wheezy', these problems have been fixed in version 1.10.1+dfsg-5+deb7u9.

We recommend that you upgrade your krb5 packages.

A use-after-free flaw was found in the way the MIT Kerberos libgssapi_krb5 library processed valid context deletion tokens. An attacker able to make an application using the GSS-API library (libgssapi) could call the gss_process_context_token() function and use this flaw to crash that application. (CVE-2014-5352)

If kadmind were used with an LDAP back end for the KDC database, a remote, authenticated attacker who has the permissions to set the password policy could crash kadmind by attempting to use a named ticket policy object as a password policy for a principal.
(CVE-2014-5353)

It was found that the krb5_read_message() function of MIT Kerberos did not correctly sanitize input, and could create invalid krb5_data objects. A remote, unauthenticated attacker could use this flaw to crash a Kerberos child process via a specially crafted request.
(CVE-2014-5355)

A double-free flaw was found in the way MIT Kerberos handled invalid External Data Representation (XDR) data. An authenticated user could use this flaw to crash the MIT Kerberos administration server (kadmind), or other applications using Kerberos libraries, via specially crafted XDR packets. (CVE-2014-9421)

It was found that the MIT Kerberos administration server (kadmind) incorrectly accepted certain authentication requests for two-component server principal names. A remote attacker able to acquire a key with a particularly named principal (such as 'kad/x') could use this flaw to impersonate any user to kadmind, and perform administrative actions as that user.

The krb5 packages have been upgraded to upstream version 1.12, which provides a number of bug fixes and enhancements, including :

  - Added plug-in interfaces for principal-to-username     mapping and verifying authorization to user accounts.

  - When communicating with a KDC over a connected TCP or     HTTPS socket, the client gives the KDC more time to     reply before it transmits the request to another server.

This update also fixes multiple bugs, for example :

  - The Kerberos client library did not recognize certain     exit statuses that the resolver libraries could return     when looking up the addresses of servers configured in     the /etc/krb5.conf file or locating Kerberos servers     using DNS service location. The library could treat     non-fatal return codes as fatal errors. Now, the library     interprets the specific return codes correctly.

In addition, this update adds various enhancements. Among others :

  - Added support for contacting KDCs and kpasswd servers     through HTTPS proxies implementing the Kerberos KDC     Proxy (KKDCP) protocol.

krb5 was updated to fix three security issues.

Remote authenticated users could cause denial of service.

On openSUSE 13.1 and 13.2 krb5 was updated to fix the following vulnerabilities :

  - bnc#910457: CVE-2014-5353: NULL pointer dereference when     using a ticket policy name as password name

  - bnc#918595: CVE-2014-5355: krb5: denial of service in     krb5_read_message On openSUSE 13.1 krb5 was updated to     fix the following vulnerability :

  - bnc#910458: CVE-2014-5354: NULL pointer dereference when     using keyless entries

The MIT Kerberos team reports :

CVE-2014-5353: The krb5_ldap_get_password_policy_from_dn function in plugins/kdb/ldap/libkdb_ldap/ldap_pwd_policy.c in MIT Kerberos 5 (aka krb5) before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service (daemon crash) via a successful LDAP query with no results, as demonstrated by using an incorrect object type for a password policy.

CVE-2014-5354: plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by creating a database entry for a keyless principal, as demonstrated by a kadmin 'add_principal -nokey' or 'purgekeys -all' command.

It was discovered that Kerberos incorrectly sent old keys in response to a -randkey -keepold request. An authenticated remote attacker could use this issue to forge tickets by leveraging administrative access.
This issue only affected Ubuntu 10.04 LTS, Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-5351)

It was discovered that the libgssapi_krb5 library incorrectly processed security context handles. A remote attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2014-5352)

Patrik Kis discovered that Kerberos incorrectly handled LDAP queries with no results. An authenticated remote attacker could use this issue to cause the KDC to crash, resulting in a denial of service.
(CVE-2014-5353)

It was discovered that Kerberos incorrectly handled creating database entries for a keyless principal when using LDAP. An authenticated remote attacker could use this issue to cause the KDC to crash, resulting in a denial of service. (CVE-2014-5354)

It was discovered that Kerberos incorrectly handled memory when processing XDR data. A remote attacker could use this issue to cause kadmind to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2014-9421)

It was discovered that Kerberos incorrectly handled two-component server principals. A remote attacker could use this issue to perform impersonation attacks. (CVE-2014-9422)

It was discovered that the libgssrpc library leaked uninitialized bytes. A remote attacker could use this issue to possibly obtain sensitive information. (CVE-2014-9423).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated krb5 packages fix security vulnerability :

In MIT krb5, when kadmind is configured to use LDAP for the KDC database, an authenticated remote attacker can cause a NULL dereference by attempting to use a named ticket policy object as a password policy for a principal. The attacker needs to be authenticated as a user who has the elevated privilege for setting password policy by adding or modifying principals (CVE-2014-5353).
