Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 : linux, linux-source-2.6.15 vulnerabilities (USN-807-1)

high Nessus Plugin ID 40416

Synopsis

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

Description

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).

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.
