Details

Michael Tokarev discovered that the RTL8169 network driver did not
correctly validate buffer sizes. A remote attacker on the local network
could send specially crafted traffic that would crash the system or
potentially grant elevated privileges. (CVE-2009-1389)

Julien Tinnes and Tavis Ormandy discovered that when executing setuid
processes the kernel did not clear certain personality flags. A local
attacker could exploit this to map the NULL memory page, causing other
vulnerabilities to become exploitable. Ubuntu 6.06 was not affected.
(CVE-2009-1895)

Matt T. Yourst discovered that KVM did not correctly validate the
page table root. A local attacker could exploit this to crash the
system, leading to a denial of service. Ubuntu 6.06 was not affected.
(CVE-2009-2287)

Ramon de Carvalho Valle discovered that eCryptfs did not correctly
validate certain buffer sizes. A local attacker could create specially
crafted eCryptfs files to crash the system or gain elevated privileges.
Ubuntu 6.06 was not affected. (CVE-2009-2406, CVE-2009-2407)
