Ubuntu 8.04 LTS / 8.10 / 9.04 : krb5 vulnerabilities (USN-924-1)

Ubuntu Security Notice (C) 2010-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

Sol Jerome discovered that the Kerberos kadmind service did not
correctly free memory. An unauthenticated remote attacker could send
specially crafted traffic to crash the kadmind process, leading to a
denial of service. (CVE-2010-0629)

It was discovered that Kerberos did not correctly free memory in the
GSSAPI library. If a remote attacker were able to manipulate an
application using GSSAPI carefully, the service could crash, leading
to a denial of service. (Ubuntu 8.10 was not affected.)
(CVE-2007-5901, CVE-2007-5971)

It was discovered that Kerberos did not correctly free memory in the
GSSAPI and kdb libraries. If a remote attacker were able to manipulate
an application using these libraries carefully, the service could
crash, leading to a denial of service. (Only Ubuntu 8.04 LTS was
affected.) (CVE-2007-5902, CVE-2007-5972).

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.

Solution :

Update the affected packages.
