Endpoint Vulnerability

Out-of-bounds write with Updater and malicious MAR file


Security researcher Holger Fuhrmannek reported that if the Updater opens a MAR format file with a specially crafted name, an out-of-bounds write will occur. This can lead to a potentially exploitable crash but requires that the malicious MAR format file be present on the local system and the Updater to be run to use it.
