medium Nessus Plugin ID 59106

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:0571 advisory.

- kernel: jbd2: unmapped buffer with _Unwritten or _Delay flags set can lead to DoS (CVE-2011-4086)

- kernel: kvm: irqchip_in_kernel() and vcpu->arch.apic inconsistency (CVE-2012-1601)

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