The host is installed with kernel through 3.18.2 and is prone to a security bypass vulnerability. A flaw is present in vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel, which does not properly choose memory locations for the vDSO area. Successful exploitation makes it easier for local users to bypass the ASLR protection mechanism.
