CVE-2019-1218
A spoofing vulnerability exists in the way Microsoft Outlook iOS software parses specifically crafted email messages.
Does this matter?
Lower severity and a low EPSS score (3.88%). Track it; it rarely justifies an emergency change on its own.
Description
A spoofing vulnerability exists in the way Microsoft Outlook iOS software parses specifically crafted email messages. An authenticated attacker could exploit the vulnerability by sending a specially crafted email message to a victim. The attacker who successfully exploited this vulnerability could then perform cross-site scripting attacks on the affected systems and run scripts in the security context of the current user. The security update addresses the vulnerability by correcting how Outlook iOS parses specially crafted email messages.
