USN-725-1: KMail vulnerability

Publication date

Overview

KMail vulnerability


Packages

Details

It was discovered that Kmail did not adequately prevent execution of arbitrary
code when a user clicked on a URL to an executable within an HTML mail. If a
user clicked on a malicious URL and chose to execute the file, a remote
attacker could execute arbitrary code with user privileges. This update changes
KMail's behavior to instead launch a helper program to view the file if the
user chooses to execute such a link.
