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: krb5-admin-server 1.12+dfsg-2ubuntu4.2 krb5-kdc 1.12+dfsg-2ubuntu4.2 krb5-kdc-ldap 1.12+dfsg-2ubuntu4.2 krb5-otp 1.12+dfsg-2ubuntu4.2 krb5-pkinit 1.12+dfsg-2ubuntu4.2 krb5-user 1.12+dfsg-2ubuntu4.2 libgssapi-krb5-2 1.12+dfsg-2ubuntu4.2 libgssrpc4 1.12+dfsg-2ubuntu4.2 libk5crypto3 1.12+dfsg-2ubuntu4.2 libkadm5clnt-mit9 1.12+dfsg-2ubuntu4.2 libkadm5srv-mit9 1.12+dfsg-2ubuntu4.2 libkdb5-7 1.12+dfsg-2ubuntu4.2 libkrad0 1.12+dfsg-2ubuntu4.2 libkrb5-3 1.12+dfsg-2ubuntu4.2 libkrb5support0 1.12+dfsg-2ubuntu4.2 Ubuntu 12.04 LTS: krb5-admin-server 1.10+dfsg~beta1-2ubuntu0.5 krb5-kdc 1.10+dfsg~beta1-2ubuntu0.5 krb5-kdc-ldap 1.10+dfsg~beta1-2ubuntu0.5 krb5-pkinit 1.10+dfsg~beta1-2ubuntu0.5 krb5-user 1.10+dfsg~beta1-2ubuntu0.5 libgssapi-krb5-2 1.10+dfsg~beta1-2ubuntu0.5 libgssrpc4 1.10+dfsg~beta1-2ubuntu0.5 libk5crypto3 1.10+dfsg~beta1-2ubuntu0.5 libkadm5clnt-mit8 1.10+dfsg~beta1-2ubuntu0.5 libkadm5srv-mit8 1.10+dfsg~beta1-2ubuntu0.5 libkdb5-6 1.10+dfsg~beta1-2ubuntu0.5 libkrb5-3 1.10+dfsg~beta1-2ubuntu0.5 libkrb5support0 1.10+dfsg~beta1-2ubuntu0.5 Ubuntu 10.04 LTS: krb5-admin-server 1.8.1+dfsg-2ubuntu0.13 krb5-kdc 1.8.1+dfsg-2ubuntu0.13 krb5-kdc-ldap 1.8.1+dfsg-2ubuntu0.13 krb5-pkinit 1.8.1+dfsg-2ubuntu0.13 krb5-user 1.8.1+dfsg-2ubuntu0.13 libgssapi-krb5-2 1.8.1+dfsg-2ubuntu0.13 libgssrpc4 1.8.1+dfsg-2ubuntu0.13 libk5crypto3 1.8.1+dfsg-2ubuntu0.13 libkadm5clnt-mit7 1.8.1+dfsg-2ubuntu0.13 libkadm5srv-mit7 1.8.1+dfsg-2ubuntu0.13 libkdb5-4 1.8.1+dfsg-2ubuntu0.13 libkrb5-3 1.8.1+dfsg-2ubuntu0.13 libkrb5support0 1.8.1+dfsg-2ubuntu0.13 In general, a standard system update will make all the necessary changes.
