Ubuntu 9.10 / 10.04 LTS / 10.10 : krb5 vulnerability (USN-1088-1)

high Nessus Plugin ID 52682

Language:

Synopsis

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

Description

Cameron Meadors discovered that the MIT Kerberos 5 Key Distribution Center (KDC) daemon is vulnerable to a double-free condition if the Public Key Cryptography for Initial Authentication (PKINIT) capability is enabled. This could allow a remote attacker to cause a denial of service.

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.
