Updated grub2 package fixes security vulnerability :
An integer overflow in liblzo before 2.07 allows attackers to cause a denial of service or possibly code execution in applications using performing LZO decompression on a compressed payload from the attacker (CVE-2014-4607).
The grub2 package is built with a bundled copy of minilzo, which is a part of liblzo containing the vulnerable code.
