Two remote code execution vulnerabilities have been reported in Microsoft Excel which could allow a remote attacker to execute arbitrary code with the privileges of the targeted user.
Description
1. Global Free Remote Code Execution Vulnerability in Excel
(
CVE-2014-6360
)
A remote code execution vulnerability exists in Microsoft Excel due to improper handling of objects in memory while processing excel documents. A remote attacker could exploit this vulnerability by enticing the user to open a specially crafted file in an affected version of Microsoft Excel.
