critical Nessus Plugin ID 77147

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

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).

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.
