CVE-2024-49039

Microsoft is reporting that a privilege escalation exists within Windows Task Scheduler that could allow a low privilege user to elevate their permissions to a Medium Integrity Level. For example, an attacker could escalate their permissions from a low privilege AppContainer to a higher integrity level and execute code.

CVE-2024-49040

A vulnerability in Microsoft Exchange Server allows non-RFC 5322 compliant P2 FROM headers to pass to the email client, which can allow the sender of an email to be spoofed. After installing the Exchange update, a new disclaimer will be prepended to the message body and a new header will be added.
