Ubuntu 6.06 LTS / 6.10 : linux-source-2.6.15/2.6.17 vulnerabilities (USN-451-1)

Description

The kernel key management code did not correctly handle key reuse. A local attacker could create many key requests, leading to a denial of service. (CVE-2007-0006)

The kernel NFS code did not correctly validate NFSACL2 ACCESS requests. If a system was serving NFS mounts, a remote attacker could send a specially crafted packet, leading to a denial of service. (CVE-2007-0772)

When dumping core, the kernel did not correctly handle PT_INTERP processes. A local attacker could create situations where they could read the contents of otherwise unreadable executable programs. (CVE-2007-0958).

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.
