Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS Summary: Several security issues were fixed in Kerberos. Software Description: - krb5: MIT Kerberos Network Authentication Protocol Details: It was discovered that Kerberos incorrectly handled certain crafted Draft 9 requests. A remote attacker could use this issue to cause the daemon to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS. (CVE-2012-1016) It was discovered that Kerberos incorrectly handled certain malformed KRB5_PADATA_PK_AS_REQ AS-REQ requests. A remote attacker could use this issue to cause the daemon to crash, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. (CVE-2013-1415) It was discovered that Kerberos incorrectly handled certain crafted TGS-REQ requests. A remote authenticated attacker could use this issue to cause the daemon to crash, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. (CVE-2013-1416) It was discovered that Kerberos incorrectly handled certain crafted requests when multiple realms were configured. A remote attacker could use this issue to cause the daemon to crash, resulting in a denial of service. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS. (CVE-2013-1418, CVE-2013-6800) It was discovered that Kerberos incorrectly handled certain invalid tokens. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be used to cause the daemon to crash, resulting in a denial of service. (CVE-2014-4341, CVE-2014-4342) It was discovered that Kerberos incorrectly handled certain mechanisms when used with SPNEGO. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be used to cause clients to crash, resulting in a denial of service. (CVE-2014-4343) It was discovered that Kerberos incorrectly handled certain continuation tokens during SPNEGO negotiations. A remote attacker could use this issue to cause the daemon to crash, resulting in a denial of service. (CVE-2014-4344) Tomas Kuthan and Greg Hudson discovered that the Kerberos kadmind daemon incorrectly handled buffers when used with the LDAP backend. A remote attacker could use this issue to cause the daemon to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2014-4345) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: Ubuntu 12.04 LTS: Ubuntu 10.04 LTS: In general, a standard system update will make all the necessary changes.

Description: | Kerberos is an authentication system which allows clients and services to authenticate to each other with the help of a trusted third party, a Kerberos Key Distribution Center (KDC). It was found that if a KDC served multiple realms, certain requests could cause the setup_server_realm() function to dereference a NULL pointer. A remote, unauthenticated attacker could use this flaw to crash the KDC using a specially crafted request. (CVE-2013-1418, CVE-2013-6800) A NULL pointer dereference flaw was found in the MIT Kerberos SPNEGO acceptor for continuation tokens. A remote, unauthenticated attacker could use this flaw to crash a GSSAPI-enabled server application. (CVE-2014-4344) A buffer over-read flaw was found in the way MIT Kerberos handled certain requests. A man-in-the-middle attacker with a valid Kerberos ticket who is able to inject packets into a client or server application's GSSAPI session could use this flaw to crash the application. (CVE-2014-4341) This update also fixes the following bugs: * Prior to this update, the libkrb5 library occasionally attempted to free already freed memory when encrypting credentials. As a consequence, the calling process terminated unexpectedly with a segmentation fault. With this update, libkrb5 frees memory correctly, which allows the credentials to be encrypted appropriately and thus prevents the mentioned crash. (BZ#1004632) * Previously, when the krb5 client library was waiting for a response from a server, the timeout variable in certain cases became a negative number. Consequently, the client could enter a loop while checking for responses. With this update, the client logic has been modified and the described error no longer occurs. (BZ#1089732) All krb5 users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the krb5kdc daemon will be restarted automatically. | ||

Description: | Kerberos is a networked authentication system which allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos KDC. It was found that if a KDC served multiple realms, certain requests could cause the setup_server_realm() function to dereference a NULL pointer. A remote, unauthenticated attacker could use this flaw to crash the KDC using a specially crafted request. (CVE-2013-1418, CVE-2013-6800) A NULL pointer dereference flaw was found in the MIT Kerberos SPNEGO acceptor for continuation tokens.

A remote, authenticated attacker could potentially use this flaw to execute arbitrary code on the system running kadmind. (CVE-2014-4345) Two buffer over-read flaws were found in the way MIT Kerberos handled certain requests. A remote, unauthenticated attacker who is able to inject packets into a client or server application's GSSAPI session could use either of these flaws to crash the application. (CVE-2014-4341, CVE-2014-4342) A double-free flaw was found in the MIT Kerberos SPNEGO initiators. An attacker able to spoof packets to appear as though they are from an GSSAPI acceptor could use this flaw to crash a client application that uses MIT Kerberos. (CVE-2014-4343) These updated krb5 packages also include several bug fixes. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.6 Technical Notes, linked to in the References section, for information on the most significant of these changes.
