Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 15.10 - Ubuntu 15.04 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in Kerberos. Software Description: - krb5: MIT Kerberos Network Authentication Protocol Details: It was discovered that the Kerberos kpasswd service incorrectly handled certain UDP packets. A remote attacker could possibly use this issue to cause resource consumption, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS. (CVE-2002-2443) It was discovered that Kerberos incorrectly handled null bytes in certain data fields. A remote attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-5355) It was discovered that the Kerberos kdcpreauth modules incorrectly tracked certain client requests. A remote attacker could possibly use this issue to bypass intended preauthentication requirements. This issue only affected Ubuntu 14.04 LTS and Ubuntu 15.04. (CVE-2015-2694) It was discovered that Kerberos incorrectly handled certain SPNEGO packets. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2015-2695) It was discovered that Kerberos incorrectly handled certain IAKERB packets. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2015-2696, CVE-2015-2698) It was discovered that Kerberos incorrectly handled certain TGS requests. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2015-2697) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 15.10: Ubuntu 15.04: Ubuntu 14.04 LTS: Ubuntu 12.04 LTS: In general, a standard system update will make all the necessary changes.

Description: | 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. | ||

Title: | AIX NAS Denial of Service via a zero-byte version string or by omitting the '\0' character | ||
Description: | MIT Kerberos 5 (aka krb5) through 1.13.1 incorrectly 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, related to appl/user_user/server.c and lib/krb5/krb/recvauth.c. | ||
