Description
A spoofing vulnerability exists in the way Microsoft Outlook for Android software parses specifically crafted email messages. An authenticated attacker could exploit the vulnerability by sending a specially crafted email message to a victim.

The security update addresses the vulnerability by correcting how Outlook for Android parses specially crafted email messages.
