Hugo Dias discovered that the ATM subsystem did not correctly manage socket counts. A local attacker could exploit this to cause a system hang, leading to a denial of service. (CVE-2008-5079)
It was discovered that the libertas wireless driver did not correctly handle beacon and probe responses. A physically near-by attacker could generate specially crafted wireless network traffic and cause a denial of service. Ubuntu 6.06 was not affected. (CVE-2008-5134)

A security issue affects these releases of Ubuntu and its derivatives:
Hugo Dias discovered that the ATM subsystem did not correctly manage socket counts. A local attacker could exploit this to cause a system hang, leading to a denial of service. (CVE-2008-5079)
It was discovered that the libertas wireless driver did not correctly handle beacon and probe responses. A physically near-by attacker could generate specially crafted wireless network traffic and cause a denial of service. Ubuntu 6.06 was not affected. (CVE-2008-5134)
It was discovered that the inotify subsystem contained watch removal race conditions. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2008-5182)
Dann Frazier discovered that in certain situations sendmsg did not correctly release allocated memory. A local attacker could exploit this to force the system to run out of free memory, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2008-5300)
It was discovered that the ATA subsystem did not correctly set timeouts. A local attacker could exploit this to cause a system hang, leading to a denial of service. (CVE-2008-5700)
It was discovered that the ib700 watchdog timer did not correctly check buffer sizes. A local attacker could send a specially crafted ioctl to the device to cause a system crash, leading to a denial of service. (CVE-2008-5702)
It was discovered that in certain situations the network scheduler did not correctly handle very large levels of traffic. A local attacker could produce a high volume of UDP traffic resulting in a system hang, leading to a denial of service. Ubuntu 8.04 was not affected. (CVE-2008-5713)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
