Ubuntu 9.10 : linux vulnerability (USN-869-1)

high Nessus Plugin ID 43097
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

David Ford discovered that the IPv4 defragmentation routine did not correctly handle oversized packets. A remote attacker could send specially crafted traffic that would cause a system to crash, leading to a denial of service. (The fix was included in the earlier kernels from USN-864-1.) (CVE-2009-1298)

Akira Fujita discovered that the Ext4 'move extents' ioctl did not correctly check permissions. A local attacker could exploit this to overwrite arbitrary files on the system, leading to root privilege escalation. (CVE-2009-4131).

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.

Solution

Update the affected packages.
