SynopsisThe remote Microsoft Exchange Server is affected by multiple vulnerabilities.
DescriptionThe remote Microsoft Exchange Server is missing a security update. It is, therefore, affected by multiple vulnerabilities :
- Multiple stack buffer overflow conditions exist in the Oracle Outside In subcomponent due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these, via a crafted file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-6013, CVE-2015-6014, CVE-2015-6015)
- An email filter bypass flaw exists in the parsing of HTML messages. An unauthenticated, remote attacker can exploit this, via specially crafted URLs in OWA messages, to identify, fingerprint, and track a user online if the user views email using Outlook Web Access.
SolutionMicrosoft has released a set of patches for Exchange Server 2007, 2010, 2013, and 2016.
