Description: | Description:
The remote host is missing an update to krb5 announced via advisory USN-587-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS Ubuntu 6.10 Ubuntu 7.04 Ubuntu 7.10
This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.
Details follow:
It was discovered that krb5 did not correctly handle certain krb4 requests. An unauthenticated remote attacker could exploit this flaw by sending a specially crafted traffic, which could expose sensitive information, cause a crash, or execute arbitrary code. (CVE-2008-0062, CVE-2008-0063)
A flaw was discovered in the kadmind service's handling of file descriptors. An unauthenticated remote attacker could send specially crafted requests that would cause a crash, resulting in a denial of service. Only systems with configurations allowing large numbers of open file descriptors were vulnerable. (CVE-2008-0947)
Solution: The problem can be corrected by upgrading your system to the following package versions:
Ubuntu 6.06 LTS: libkadm55 1.4.3-5ubuntu0.7 libkrb53 1.4.3-5ubuntu0.7
Ubuntu 6.10: libkadm55 1.4.3-9ubuntu1.6 libkrb53 1.4.3-9ubuntu1.6
Ubuntu 7.04: libkadm55 1.4.4-5ubuntu3.4 libkrb53 1.4.4-5ubuntu3.4
Ubuntu 7.10: libkadm55 1.6.dfsg.1-7ubuntu0.1 libkrb53 1.6.dfsg.1-7ubuntu0.1
In general, a standard system upgrade is sufficient to effect the necessary changes.
