1) Input validation error (CVE-ID: CVE-2013-0228)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

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.
