Description

This security bulletin contains information about 1 security vulnerability.


1) Cross-site scripting (CVE-ID: N/A)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via SVG images. A remote attacker can send a specially crafted email message that contains a malicious SVG image and and execute arbitrary HTML and script code in user's browser in context of Outlook on the web (formerly known as Outlook Web App) website.
