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

critical Nessus Plugin ID 65123

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.
