Oracle Linux 5 / 6 : Unbreakable Enterprise kernel (ELSA-2013-2507)

high Nessus Plugin ID 68847

Synopsis

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

Description

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2013-2507 advisory.

- arch/x86/include/asm/pgtable.h in the Linux kernel before 3.6.2, when transparent huge pages are used, does not properly support PROT_NONE memory regions, which allows local users to cause a denial of service (system crash) via a crafted application. (CVE-2013-0309)

- The cipso_v4_validate function in net/ipv4/cipso_ipv4.c in the Linux kernel before 3.4.8 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an IPOPT_CIPSO IP_OPTIONS setsockopt system call. (CVE-2013-0310)

- The translate_desc function in drivers/vhost/vhost.c in the Linux kernel before 3.7 does not properly handle cross-region descriptors, which allows guest OS users to obtain host OS privileges by leveraging KVM guest OS privileges. (CVE-2013-0311)

- The xen_iret function in arch/x86/xen/xen-asm_32.S in the Linux kernel before 3.7.9 on 32-bit Xen paravirt_ops platforms does not properly handle an invalid value in the DS segment register, which allows guest OS users to gain guest OS privileges via a crafted application. (CVE-2013-0228)

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.
