Säkerhetsuppdateringar från Apple
Apple släppte igår en stor mängd säkerhetsuppdateringar till iOS, macOS, watchOS samt tvOS. En eller flera av dessa åtgärdar säkerhetsbrister som gör att en angripare kan exekvera kod över nätverket.
Även så åtgärdas tre kryptobuggar där två av dessa är relaterade till S/MIME (e-postkryptering):
- A S/MIME encrypted email may be inadvertently sent unencrypted if the receiver’s S/MIME certificate is not installed
- An encryption issue existed with S/MIME credetials. The issue was addressed with additional checks and user control.
- OpenSSL X.509 IPAddressFamily parsing
