Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2011-0928 advisory.

- net/ipv4/ip_gre.c in the Linux kernel before 2.6.34, when ip_gre is configured as a module, allows remote attackers to cause a denial of service (OOPS) by sending a packet during module loading. (CVE-2011-1767)

- The tunnels implementation in the Linux kernel before 2.6.34, when tunnel functionality is configured as a module, allows remote attackers to cause a denial of service (OOPS) by sending a packet during module loading. (CVE-2011-1768)

- The Linux kernel before 2.6.39 does not properly create transparent huge pages in response to a MAP_PRIVATE mmap system call on /dev/zero, which allows local users to cause a denial of service (system crash) via a crafted application. (CVE-2011-2479)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
